How Often Baby Pee

Your baby may pee as often as every 1.5 to 2 hours or as infrequently as 4 to 6 times a day. If your baby has a high fever or is dehydrated, his usual output of urine may drop by half and still be a normal amount.

Wondering how often your baby should urinate? Here’s the lowdown. Just after birth, your newborn should urinate within the first 24 hours. Soon after, your baby will have their first wet diaper (you may not notice until they’ve already

After your baby is born, it’s normal for them to urinate often and then not so often, then often again. When they’re about 3 month old and only drinking breast milk or formula, they’ll urinate up to seven times a day. If they start eating solids, the frequency will decrease to five or six times a day. During tummy time, babies tend to urinate more frequently too. The diaper usually feels heavier when it’s full of urine. If your baby starts going longer periods between changes, or if their diaper is much lighter than usual, this can be another sign that they’re dehydrated.

For healthy babies, the usual frequency of urination can vary from several times a day to once every few days.

Expect your newborn to wet at least six diapers a day for the first three months.

How often a parent can expect their baby to urinate or wet their diaper each day.

Many new parents wonder what’s normal and what’s not when it comes to diapering their​ newborn. Here’s what you can expect during your baby’s first few days.

Wet Diapers in the First Week of Life

Breastfeeding moms are often more concerned about wet diapers than moms who bottle-feed. It’s easier to tell that the baby is getting enough to eat when you’re giving a bottle. When you’re breastfeeding, however, it can be a little more difficult—especially in the first few days while your supply of breast milk is increasing.1

Counting wet diapers is a great way to help you feel more confident that your baby is getting what they need.2 Here’s how many wet diapers to expect during the first week for babies who breastfeed and those who take a bottle.

Breastfed Infants

The number of wet (urine) diapers a breastfed baby has each day changes during the first week of life. During the first few days, your newborn may not receive much breast milk so they won’t have many wet diapers. Then, as the days go on and your supply of breast milk increases, your baby will produce more urine and have more wet diapers.Featured Video seconds of 1 minute, 45 secondsVolume 0%01:45 How to Burp a Baby

Here’s what to expect:

  • Day 1: A newborn baby will pass urine for the first time within 12 to 24 hours of birth. During the early hours and days of life, an exclusively breastfed baby may not have many wet diapers.
  • Day 2: You should look for at least two wet diapers a day until your breasts begin to fill with milk by the third or fourth day postpartum; as your milk supply increases, so will the wet diapers.
  • Days 3–5: Your baby should have at least three to five wet diapers.
  • Day 6 and on: Your baby should be having at least six to eight wet diapers every 24 hours but may have more; some babies have a wet diaper at every feeding.

Bottle-Fed Infants

Even if you bottle-feed, your baby may not take much formula or pumped breast milk during the first day or two after birth. The amount of urine that your newborn produces is directly related to the amount of fluid they take in.

If your baby is a great eater and takes 2 ounces of formula every three hours right from the beginning, you will see more wet diapers. But, if your newborn is sleepy or not taking in much fluid during the first day or so, they’ll have less wet diapers.

Here is a general guide:

  • Day 1: Your baby should have their first wet diaper by the time they are 12 to 24 hours old.
  • Day 2: You should look for at least two wet diapers a day.
  • Days 3–5: Baby should have at least three to five wet diapers.
  • Day 6 and on: You should expect at least six to eight wet diapers a day.

Urination After the First Week

Whether you’re bottle-feeding or breastfeeding, your newborn should be settling into a feeding pattern and eating well by the second week of life. You should see at least six to eight wet diapers each day,3 but your child could have up to 10 or more.

A newborn’s little bladder holds about one tablespoon (15 mL) of urine,4 so they may empty it very often. Some newborns will pee up to 20 times in 24 hours, and that’s OK. If your baby is sleeping, you don’t have to wake them up to change a diaper. A change before or after each feeding, approximately every two to three hours, is fine.5

How to Check a Diaper for Wetness 

Since newborns only make a small amount of urine and disposable diapers are very absorbent, it can be hard to tell if the diapers are wet and your baby is peeing enough. So, here are some ways to make sure your child is wetting the diaper:

  • After you change your baby, take the diaper apart to check the under layers or gel material for moisture. It’s OK to touch and smell the diaper to check for urine.
  • Place one tissue into your baby’s diaper to absorb the urine and make it easier to see.
  • Pour 1 ounce (2 tablespoons, 30 milliliters) of water into a clean, dry diaper. It will give you a better idea of how a wet diaper looks and feels.
  • Try cloth diapers. You may find it easier to see and feel the wetness in a cloth diaper than in a disposable diaper.
  • Try disposable diapers with a wetness indicator, which is a line or design that changes color when urine is present.

The Color of Newborn Urine

Your baby’s urine should be colorless or light yellow.6 However, if you’re breastfeeding, you may notice some slight color changes once in a while. Certain foods, food dyes, herbs, and vitamin supplements that you add to your everyday diet could change the color of your breast milk as well as add a tint of green, pink, or orange to your newborn’s urine.

Concentrated Urine

Concentrated urine is very dark yellow.6 It may also have a strong smell. After your milk comes in, a diaper with concentrated urine now and then is OK. However, if your baby has many diapers with very dark yellow urine, call the doctor.

Brick Dust Urine

Very concentrated urine during the first few days of life can contain urate crystals (uric acid crystals). These urate crystals can cause a pink, red, or orange-colored, powdery stain in your baby’s diaper called brick dust.7 It might be scary, but brick dust is normal for many newborns. Concentrated urine and brick dust should go away by the fifth or sixth day when you’re making more breast milk.

Blood in the Diaper

Both boys and girls can have a little blood in their diaper, but for different reasons. Here are two reasons you may notice blood that aren’t serious:

  • Pseudomenstruation: Baby girls may have blood-tinged vaginal discharge during the first few days of life.8 It’s called pseudomenstruation, or false menstruation. It is from the hormones in your baby’s body, and it’s not harmful.
  • Circumcision: Baby boys may have a small amount of blood in their diapers after a circumcision. The bleeding from a circumcision usually lasts for a few hours, but you may notice small spots of blood in the diaper for up to a day. After the circumcision, your baby should have a wet diaper within 12 hours.

When to Call Your Baby’s Doctor

When your baby is getting enough fluids, they will have at least six to eight wet diapers a day. But, if your baby is not getting enough, they can become dehydrated. Dehydration in newborns and young infants is dangerous.

The doctor will check your child’s health and talk to you about how much and how often your baby is eating.

Notify the doctor if:

  • The baby has fewer than six wet diapers each day after day five.
  • The baby is only making a small amount of very dark yellow, concentrated, smelly urine after day four.6
  • The baby is unusually sleepy and difficult to wake.
  • The baby’s mouth and lips are dry.9
  • The soft spot on top of the baby’s head is sinking down into their head.9
  • Your baby is not feeding well.
  • You see brick dust stains in your newborn’s diaper after the fourth day of life.

When a Newborn Is Not Urinating

Your child should have at least two wet diapers during the first few days when you’re only making colostrum. But, by the time your baby is six days old, they should have at least six wet diapers a day. If your child is not making enough urine or has no urine at all, call the doctor immediately.

Blood in Newborn Urine

While a little blood in your baby’s diaper from circumcision or pseudomenstruation is OK, blood in your baby’s urine is not. If you see any blood in your little one’s urine or your child is crying and showing signs of painful urination, contact your baby’s doctor right away.

Signs of a Urinary Tract Infection

If bacteria gets into the baby’s urinary tract, it can cause an infection. A urinary tract infection (UTI) can change the amount, color, or smell of your baby’s urine.

These are some ways to prevent a UTI:

  • Change your baby’s diaper often especially after bowel movements.
  • Clean your baby’s diaper area from front to back.
  • Make sure your baby is getting enough breastmilk or formula.
  • Wash your hands before and after changing your baby.

It can be difficult to notice a UTI in babies, but the symptoms to watch for include:10

  • Blood in the urine
  • Fever
  • Frequent urination
  • Pain when peeing
  • Smelly urine

If you see these signs of a UTI, you should call your baby’s doctor for treatment.

A Word From Verywell

Babies are all different. Some breastfeed, and others take a bottle. Some are alert and eat well from the first feeding, and others are sleepy for a few hours or days. These are some of the reasons there’s a wide range of normal when it comes to newborn urination.

By understanding the guidelines and monitoring your baby’s wet diapers, it can help you feel more confident that your baby is making enough urine and getting enough fluids. Of course, if you have any questions about the amount, color, or frequency of your baby’s urination, you should call the doctor. The staff at your doctor’s office is there to help.

Newborn Baby Urine Problem

Many new moms have questions about their baby’s urination pattern. You may be wondering how many wet diapers your baby should have each day, what color baby’s urine should be, and what you should be checking for at each diaper change. Here you find information and guidelines for what’s normal and what’s not.


Your baby may urinate as often as every one to three hours or as infrequently as four to six times a day. If they’re ill or feverish, or when the weather is extremely hot, their usual output of urine may drop by half and still be normal.

Urination should never be painful. If you notice any signs of distress while your infant is urinating, notify your pediatrician. This could be a sign of infection or some other problem in the urinary tract.

In a healthy child, urine is light to dark yellow in color. (The darker the color, the more concentrated the urine; the urine will be more concentrated when your child is not drinking a lot of liquid.) In the first week after birth, you may see a pink or brick-red stain on the diaper, often mistaken for blood. In fact, this stain is usually a sign of highly concentrated urine, which has a pinkish color. As long as the baby is wetting at least four diapers a day, there probably is no cause for concern. If the pinkish staining persists, consult your pediatrician.

Newborn girls may have a small spot of blood in the diaper, also usually in the first week after birth; this blood is caused by her mother’s hormones affecting the baby’s uterus. After that time, however, the presence of actual blood in the urine or a bloody spot on the diaper is never normal, and your pediatrician should be notified. It may be due to nothing more serious than a small diaper rash sore, but it also could be a more serious problem. If this bleeding is accompanied by other symptoms, such as abdominal pain, poor feeding, vomiting, fever, or bleeding in other areas, seek medical attention immediately.

Bowel movements

For the first few days after birth, your baby’s first bowel movements will be a substance known as meconium. This thick black or dark green substance filled their intestines before birth, and once passed, the stools turn yellow-green.

Baby stools vary in color and consistency due to their immature digestive system. If your baby is breastfed, their stools soon should be yellow liquid mixed with some particles. Until they start to eat solid foods, the consistency of the stools may range from very soft to loose and runny. If they’re formula-fed, their stools usually will be tan or yellow in color. They will be firmer than a breastfed baby’s, but should be no firmer than soft clay. Green stools are not unusual, either, and they should not cause you alarm.

Whether your baby is breastfed or bottle-fed, hard or very dry stools may be a sign that she is not getting enough fluid or that she is losing too much fluid due to illness, fever, or heat. Once solids are introduced, hard stools might indicate that she’s eating too many constipating foods, such as cereal or cow’s milk, before her system can handle them. (Whole cow’s milk is not recommended for babies under twelve months.)

Here are some other important points to keep in mind about bowel movements:

  • Occasional variations in color and consistency of the stools are normal. For example, if the digestive process slows down because of foods requiring more effort to digest (such as large amounts of cereal), the stools may become green; or if the baby is given supplemental iron, the stools may turn dark brown. If there is a minor irritation of the anus, streaks of blood may appear on the outside of the stools. However, if there are large amounts of blood, mucus, or water in the stool, call your pediatrician immediately. These symptoms may warrant attention from your doctor.
  • Because an infant’s stools are normally soft and a little runny, it’s not always easy to tell when a young baby has mild diarrhea. The telltale signs are a sudden increase in frequency (to more than one bowel movement per feeding) and unusually high liquid content in the stool. Diarrhea may be a sign of intestinal infection, or it may be caused by a change in the baby’s diet. If the baby is breastfeeding, they can even develop diarrhea because of a change in the mother’s diet.
  • The main concern with diarrhea is the possibility of dehydration. If fever is also present and your infant is less than three months old, call your pediatrician. If your baby is over three months and the fever lasts more than a day, check her urine output and rectal temperature; then report your findings to your doctor for consideration. Make sure your baby continues to feed frequently. As much as anything else, if they simply looks sick, let your doctor know.

The frequency of bowel movements varies widely among babies. Many pass a stool soon after each feeding. This is a result of the gastrocolic reflex, which causes the digestive system to become active whenever the stomach is filled with food.

By three to six weeks of age, some breastfed babies have only one bowel movement a week and still are normal. Breast milk leaves very little solid waste to be eliminated from the child’s digestive system. Thus, infrequent stools are not a sign of constipation and should not be considered a problem as long as the stools are soft, and your infant is otherwise normal, gaining weight steadily, and nursing regularly. Babies with this breastfed stool variant usually have a large volume of stool if it has been a few days (so you should be prepared with lots of wipes to clean up).

If your baby is formula-fed, they should have at least one bowel movement a day. If they have fewer than this and appear to be straining, they may be constipated. Check with your pediatrician for advice on how to handle this problem.
