7 Baby Development Milestones To Watch Out For In Their First 6 Months

baby development milestones

There are many baby development milestones to watch out for as your child grows. Between the ages of 0-6 months, there are seven key milestones that babies typically reach. Each milestone is an important step in their development and marks a new level of growth and understanding.

Here’s a look at those seven baby development milestones to watch for during your child’s first six months. Don’t forget to check out this complete developmental chart for babies and toddlers. 

Let’s dive right in!


Smiling as one of baby development milestones

Smiling is one of the first baby development milestones to remember. Remember how your baby couldn’t stop smiling at you when they were born? Babies start developing this muscle between the ages of two weeks and three months. Yup, that’s pretty early! Smiling is usually the first sign of social interaction and is your baby’s way of communicating with you.

You can expect them to be smiling all the time (and you will too)! This is a good milestone for parents because it means that their child is happy, healthy, and developing normally.

Recognizing Faces 

The second baby development milestone that you can expect to see is your child recognizing faces. This means that, when they look at someone’s face, their eyes will move from side to side and take in the whole picture.  This milestone usually occurs around two to four months old.

One way to help your child with this milestone is by talking to them and pointing out different aspects of people’s faces. For example, you can say “Mommy has green eyes like a cat!” or “Daddy has a big nose!” This will help your child understand that people look different.

At this age, the best thing you can do is to keep socializing with your baby and exposing them to other faces (and places), so they get used to how things actually are!

While it might not seem like much now – this skill is an important step in your baby’s development!


Another one of the baby development milestones that you can expect during a child’s first six months is babbling.  Babies start babbling between the ages of four and seven months, but it might be hard to distinguish at first. 

You can expect to hear “ba-ba”, “da-da”, etc. – even though they aren’t actually saying those words yet! This is a milestone because your child starts practicing their language skills early on.

You will notice them making a lot of noise, but they won’t have any real words yet! This milestone typically occurs when babies are between two to four months old. It’s an important step in their language development, so make sure to listen and talk to them often!


At four months old, you can expect your baby to start moving around on his own. They will start to crawl or scoot around, and their movements will become more purposeful. As a parent, you can help develop fine motor skills. 

This is the time when they begin trying to use objects in new ways (like shaking a rattle). At this stage of development, you can expect your baby to spend most of their waking hours on the move!

They will still be wobbly and uncoordinated, but they will get the hang of moving around on their own eventually. This is a big step towards them being able to crawl and walk!

Babies learn best through movement, so this is a great milestone!

 Learning and Socializing

When babies reach five months old, they start to learn about their surroundings.  This includes learning about people, objects, and what is happening around them. They will also start interacting with those around them more – this could involve smiling at you, cooing, or even laughing!

Moreover, they start to figure out what is around them, and they learn how to make the connection between an object itself and its use. This can happen in a variety of ways – for example; your baby might understand that their bottle will provide food when you tap on it! 

Babies at this age are social beings as well. They love playing with other babies and adults that they trust. Babies will start to socialize at this age, so be sure to have lots of visitors!

This is one of the important baby development milestones because it lays the groundwork for future social interactions.

The sixth milestone is communication. This usually starts happening around four to six months old.  Your baby will probably start using gestures to communicate their needs, which is great because it means that they are learning how to express themselves. 

This milestone usually includes them being able to respond when you talk directly to them or wave goodbye!

Babies will start making noises and trying to communicate with you. They might also start cooing or babbling at this stage.


The seventh baby development milestone is emotions. This usually occurs between four and six months old.  Your baby will show their feelings through facial expressions, crying, and bodily movements. They will start using different tones of voice depending on the situation (happy or sad).

Moreover, your baby will start recognizing and responding to different emotions. This is a big step in their development, so let them experience all of the different kinds of feelings that they want!

It’s an important step in developing empathy towards others!
