Developmental Milestones For Infant

The first year of your baby’s life is a time for you to watch and wait. You’ll see your baby grow and change every day, but don’t worry if things don’t always happen at the same pace. Although everyone develops differently, here are some of the things you can expect from your child between 2 months and one year old:

During your child’s first years, you’ll be watching for many different developmental milestones. Each one is a sign that your child’s brain is making new connections, which will help him or her learn and grow.

When it comes to learning, babies develop at different rates.

When your child learns something new, you’ll see it in his or her behavior: Your baby might reach for a toy or smile when you talk to him or her. As your baby grows, he or she will learn more complex skills like crawling and walking.

As your child gets older, he or she will continue learning through play with toys and other objects around the house. He or she may also explore by putting things in mouth and looking at books with pictures of familiar things (like Mommy).

Your baby’s brain is forming connections between its neurons every second of every day! This makes sense because everything we experience affects us on some level – even if we don’t always notice these changes right away. Babies are especially sensitive to their environments since they’re developing so rapidly during those first few years after birth when many important neuropathways are being laid down within their brains; this includes how much stimulation they receive from people around them like parents/caretakers who read stories aloud each night before bedtime –

By 2 months old, your baby may:

By 2 months old, your baby may:

  • Respond to sound. Your baby may startle when she hears a loud noise and turn her head toward the source of the sound. She will also begin to make her own noises, such as by cooing or crying.
  • Respond to light. Your baby may startle when she looks at something bright, such as a flash from a camera or lamp. Her eyelids may blink in response to this bright light and you can see that her pupils are constricted (small).
  • Babble and make sounds with his voice. Baby’s babbling is an important way for him to learn how language works by experimenting with sounds that he makes himself! If he doesn’t stop babbling for several minutes at a time yet, it might be because he hasn’t figured out how words work yet—in other words: don’t be worried if there isn’t much language coming out of his mouth yet! Baby babblings are still very important because they show us how our child communicates even though they aren’t words just yet; we need this information so that we can help them learn how language works later on in life too!

By 4 months old, your baby may:

  • Coo and babble.
  • Smile in response to familiar faces.
  • Reach out for things.
  • Recognize familiar objects.
  • Follow a series of events with your eyes.
  • Bring hands together (for example, bring the thumb to the mouth).
  • Make sounds while looking at you

By 6 months old, your baby may:

  • talk to you in single words
  • reach for objects
  • roll over
  • babble, or make sounds that mean something like “mama,” “dada,” and “bye bye” (8 to 10 months)
  • look at you when you talk to them (8 to 10 months)
  • follow simple instructions like “Show me your nose” or “Give me your toy” (6 to 9 months), or point out their toys when asked by an adult!

By 9 months old, your baby may:

By 9 months old, your baby may:

  • Hold her head up for long periods of time.
  • Roll over from front to back and back to front.
  • Sit up with some support. She still needs help balancing because her head is heavy and she can’t control it well yet.
  • Babbles, tries to imitate sounds she hears around her, or makes other noises as if trying out different words.
  • Sit without support for a few seconds at a time; may still need help balancing when sitting upright without support (as when in the high chair). This milestone is important because it allows your child to begin learning how to crawl, which will happen soon!

By 12 months old, your baby may:

By 12 months old, your baby may:

  • Use words to communicate.
  • Say at least 10 words.
  • Point to objects when asked.
  • Understand simple commands and directions (such as “no” and “come”).
  • Show interest in other people and things with gestures, sounds, or eye contact.

If you have a child who is very social by nature, he or she may imitate your facial expressions and sounds at an earlier age than infants who are less socially oriented.

By 15 to 18 months old, your baby may:

By 15 to 18 months old, your baby may:

  • Use words to communicate.
  • Understand simple instructions.
  • Point to familiar objects.
  • Imitate your actions (for example, clapping hands).

By 20 to 30 months old, your child may:

By 20 to 30 months old, your child may:

  • Talk in short sentences. She’ll understand more than 50 words and use them correctly to describe her feelings or needs. She may also use several words together in a sentence, such as “Mommy go away.”
  • Understand the difference between fantasy and reality. Your child will understand that what happens in books, movies and cartoons can’t really happen in real life — for example, monsters don’t really exist! Her playtime is often filled with imaginative scenarios based on what she’s seen or heard from others — so be prepared for some strange conversations! For example: “Mommy please make me dinner.”
  • Play pretend games with you using household objects as props such as “cooking” dinner for her stuffed animals with pots made out of empty boxes or pretending these toys are people who live at an imaginary house (e.g., “Let’s go visit Grandma”).

Between the ages of 2 and 3 years, most children can do all these things. If there’s something on the list that worries you about your child (for instance, he or she isn’t babbling as much as other kids), talk with his or her doctor about it. It’s possible for children to develop at slightly different paces. If the doctor thinks this might be the case with your child, she may recommend some kind of evaluation or therapy.

Your doctor is a great resource for information about your child’s development. He or she may be able to help you figure out whether something seems off with your child’s development. If so, the doctor may recommend that you make an appointment with a specialist who can give you more information about why your child might not be developing at the same rate as other kids his age.

The most important thing is to talk to your doctor if something seems off with your child’s development, even if it doesn’t feel like a big deal. You don’t want to ignore anything that could have serious consequences down the road!


If you’re concerned about your child’s development, talk with his or her doctor. He or she can help you figure out what might be going on and suggest ways to support your child’s growth. If the doctor thinks this might be something that needs more specialized attention like speech therapy, he or she may recommend an evaluation by a pediatrician who specializes in identifying developmental delays.
