3-month-old baby development

Are you exhausted? The “worst part” is soon over now. With a 3-month-old baby, many new parents notice that life with the new baby slowly becomes easier.


Well, colic and stomach pain usually decline. The baby is more communicative and easier to understand and help.

Some babies start sleeping better and eat less often.

Now, what can you expect from a 3-month-old baby?

A wonderful thing is that he or she is likely to be very fond of you and really show it.

All About The 3-Month-Old Baby

3-Month-Old Baby Development Milestones

Here’s what is probably going on with your baby right now.

Social Development

Every week that passes, your 3-month-old baby will become more and more open to other people.

On the other hand, he will really have realized who is his closest family. Mom, dad and possibly also his siblings are his real favorites.

A fun thing to notice is that without thinking, you probably use a very light and soft voice when talking to your baby. That is nature’s way of making sure that the baby knows that he is being talked to and that no one will scare him by talking aloud to him.

A wonderful milestone of your 3-month-old baby is that their crying often subsides and that other ways of communicating increase. Your baby will smile, coo, and wave his or her arms, for example.

Physical Development

Your baby’s motor skills, coordination, and strength are developing rapidly.

Your baby becomes stronger and more steady and might discover how fun it is to stand up with straight legs. My daughter did this early and everywhere. It even became a hassle to change her diapers because she refused to bend her legs.

As their neck and upper body muscles strengthen, most babies are now also able to support themselves and hold their heads up and support themselves on their arms (not hands) for a while if placed on their tummy. You’ll find tummy time tips here.

Hand-eye coordination is improving and soon enough your baby will start reaching for and grabbing anything within reach. Something to remember if you have your baby on your lap while having dinner!

Your baby will put their hand in their mouth and can probably also grab and hold something for a little while.

Your baby will move around more and can probably roll over from side to back. They also kick their legs with more strength. This makes leaving the baby alone on the bed, sofa or changing table very dangerous, even for a minute!

3-Month-Old Baby Senses

Your baby’s senses continue to improve. As their vision is developing, many babies now love to look at faces. This is why an unbreakable mirror can be a great toy to place in the crib or in front of the baby for tummy time.

With stronger muscles and better hearing, your baby is also likely to turn his or her head towards your voice.

Games To Play

Talk to your baby!
Research indicates that if parents talk to their children, they (the babies… ;-D ) actually get a higher IQ. If it is hard to find something to talk about, simply explain to your baby what you’re doing, point to things you walk by or tell him/her your inner thoughts. Right now, your baby is not picky!

The strongest connection between IQ and conversation is found for toddlers between 18 and 24 months, but there is evidence for babies as young as 3 months, so do what you can to talk to your baby! (Research reference here)

Let your baby look at new objects often. Colorful new shapes are often very exciting. Also, research indicates that also this, to see new things, often generates a higher IQ.

Many babies love flying! Lie down on your bed and lift your baby up into the air. If you start every flying session with a slow “One two three” or something like that, your baby will soon know what to expect and start smiling long before he or she is actually flying. Make him crash slowly towards your face for a kiss!

Flying is actually an excellent game to strengthen a baby’s back muscles. For more ideas to help your baby endure the tummy time, click here.

Toy Tips

At three months, the baby gym is likely to be a favorite. A fun time for your baby, some spare time for you! Baby Einstein has a gym with a built-in mirror and playmat. Great for this age! Check it out at Amazon here.

Since your baby might endure longer periods on his tummy now, it is a good idea to invest in some sort of baby play mat – if you bought the baby gym separately.

A baby-safe unbreakable mirror can be fun for the 3-month-old AND a great way to spend tummy time, which is otherwise something small babies often hate.

All sorts of rattles for babies are fun too!
