How Long Can A Newborn Go Without Eating After Birth

Newborns should not go more than about 4–5 hours without feeding. Signs that babies are hungry include: moving their heads from side to side.

In general, newborns should not go longer than 4–5 hours without feeding. If you think your infant is hungry (they move their heads from side to side), give them some breast milk or formula.

Newborns can go without eating for a few hours, but there are risks of dehydration and upset stomachs.

Your newborn’s stomach will develop over the next several days, so they won’t need to eat as often. If you do notice your baby isn’t eating (or when you wipe off her chin there isn’t any food in it), try several of our recommended formulas and see if your baby wants to eat.

Signs of Poor Feeding in Newborn

Your newborn will nurse about 8 to 12 times per day during the first weeks of life. In the beginning, mothers may want to try nursing 10–15 minutes on each breast, then adjust the time as needed.

Breastfeeding should be on demand (when your baby is hungry), which is generally every 1–3 hours. As newborns get older, they’ll nurse less often and have longer stretches between feedings. Newborn babies who are getting formula will likely take about 2–3 ounces every 2–4 hours. Newborns should not go more than about 4–5 hours without feeding.

Signs that babies are hungry include:

  • moving their heads from side to side
  • opening their mouths
  • sticking out their tongues
  • placing their hands and fists to their mouths
  • puckering their lips as if to suck
  • nuzzling against their mothers’ breasts
  • crying

A feeding schedule is not necessary — you and your baby will get into a routine. Babies know (and will let their parents know) when they’re hungry and when they’ve had enough. Watch for signs that your baby is full (slowing down, spitting out the bottle or unlatching from breast, closing the mouth, turning away from the breast or bottle) and stop the feeding when these signs appear.

As babies grow, they begin to eat more at each feeding and can go longer between feedings. There may be other times when your infant seems hungrier than usual. Continue to nurse or feed on demand. Nursing mothers need not worry — breastfeeding stimulates milk production, and your supply of breast milk will adjust to your baby’s demand for it.

Is My Newborn Getting Enough to Eat?

New parents often worry about whether their babies are getting enough to eat.

Babies are getting enough to eat if they:

  • seem satisfied
  • have about 6–8 wet diapers a day
  • have regular bowel movements (poops)
  • sleep well
  • are alert when awake
  • are gaining weight

A baby who is fussing, crying, seems hungry, does not appear satisfied after feeding, and has fewer wet diapers may not be getting enough to eat. If you’re concerned that your baby isn’t getting enough to eat, call your doctor.

Most infants “spit up” a small amount after eating or during burping, but a baby should not vomit after feeding. Vomiting after every feeding might be a sign of an allergy, digestive problem, or other problem that needs medical care. If you have concerns that your baby is spitting up too much, call your doctor.

Should Newborns Get Nutritional Supplements?

Breast milk has the right combination of vitamins and easily absorbed iron for newborns. A healthy infant being nursed by a healthy mother doesn’t need extra vitamins or nutritional supplements, with the exception of vitamin D. Breastfed babies should begin vitamin D supplements within the first few days of life, continuing until they get enough vitamin D-fortified formula or milk (after 1 year of age).

Breastfeeding mothers who follow vegetarian diets that do not include animal products need vitamin B12 supplements.

Iron-fortified formula has the right blend of vitamins and minerals for a baby, so supplements usually aren’t needed. Infants drinking less than 1 liter, or about a quart, of formula a day may need a vitamin D supplement.

Water, juice, and other foods usually aren’t necessary during a baby’s first 6 months. Breast milk and formula provide everything babies need nutritionally until they start eating solid foods. Talk to your doctor if you have any questions about feeding your newborn.

Newborn Not Feeding First 24 Hours

The first day of your new baby’s life is thrilling and exhausting for both of you. This page explains what your newborn baby can sense, and how the umbilical cord and placenta can be managed. It has general information for you if you have had a healthy, full-term pregnancy – 37 to 42 weeks’ gestation.

What will my newborn baby look like?

When your baby is born, their skin might be blue and mottled. They are likely to be covered in amniotic fluid, blood and vernix, which is a cheesy white substance. This is normal.

Their skin will start to become pink as they start to breathe — which is about a minute after birth. Your baby’s hands and feet may still appear blueish for several hours.

The amniotic fluid and the vernix are there because they were there in the womb. They are important for your baby to be able to smell and taste after birth. These familiar things help your baby to feel secure outside the womb.

Birth of the placenta and cutting the umbilical cord

After you have given birth to your baby, you will have more contractions that will help you deliver the placenta. Once this happens, the umbilical cord, which is connected to the placenta, will be clamped in two places and cut. Your support person might be invited to cut the cord.

Skin-to-skin contact

After a normal vaginal birth, your newborn baby will be put on your chest for skin-to-skin contact. Your baby needs sleep and food, and they need to feel secure and warm, so they need to feel your skin.

Doing this simple thing:

  • reduces newborn crying
  • helps start and sustain breastfeeding
  • helps maintain your baby’s body temperature

After this first contact, they will be weighed, measured and observed to make sure they are healthy.

If you have a caesarean section, ask your midwife to make sure your baby has skin-to-skin contact with you as early as possible. It may be possible for you or your partner to hold your baby-skin-to skin in theatre and in recovery.


Babies start to show signs of wanting to feed soon after birth and usually attach and suck at the breast about 50 minutes after birth. They may then breastfeed for an hour or more. Put your baby against your chest, and they will probably find your breast and start feeding. If that doesn’t happen, you can ask your midwife or a lactation consultant for help.

The first milk you make is called ‘colostrum’. It’s thick and often yellowish, rather than pure white. It’s the ideal milk for your baby. Normally a small amount is produced — your baby’s tummy is just the size of a marble.

If they haven’t fed an hour or so after birth, try again a couple of hours later. You can also express some colostrum to feed to your baby on a spoon.

Weighing and measuring

After skin-to-skin contact and the first breastfeed, your midwife might offer to weigh your baby, and measure your baby’s length and head circumference. Your baby doesn’t need to be washed for at least 24 hours.

Vitamin K

At the time of weighing, your midwife will also offer to give your baby a vitamin K injection to prevent bleeding from vitamin K deficiency.

Cord blood collection if you are Rh negative

If your blood group is Rh negative, some blood will be taken from the umbilical cord to determine whether your baby’s blood group is compatible.


Your baby will stay with you so you can bond and respond easily to their needs. They’ll probably sleep soon after their first feed, and that might last 6 hours or so. They will probably sleep for more than half of their first day in the world.

Apgar scores

One of the main observations made after birth is called an Apgar score. It assesses your baby’s adjustment to life outside the womb. The Apgar score is measured at 1 minute and 5 minutes after birth while the baby is on your chest. Sometimes it is measured again at 10 minutes after birth.

It records your baby’s heart rate, breathing, colour, muscle tone and reflexes. The maximum score is 10. A score of 7 or above usually means your baby is doing well. It is not an ability or intelligence test, and it doesn’t predict your baby’s health later in life.

What will my newborn baby see, hear, smell, taste and feel?

Your baby has been listening to your voice for the last half of your pregnancy and will recognise it when you speak to them after birth. Your partner or support person’s voice may also be familiar if they have also been talking near your baby. Your baby will feel secure when they hear your voices and may respond by turning their head towards you. Your baby will also be able to hear your heart beating as they did in the womb.

Your baby’s vision is blurred at birth but they will be able to focus on your face from about 30 centimetres away. This is called the ‘cuddle distance’. It is roughly the distance from your breast to your face. Your baby will make the connection between what they hear and what they see.

Your baby will smell and taste the amniotic fluid and your colostrum, which has a similar flavour.

Urine and meconium

Within the first 24 hours your baby will probably pass urine and meconium (newborn faeces) at least once. Meconium is black and sticky. Your baby’s poo will change colour and consistency over the next few days.
