Especially for new parents, taking a newborn home is always exciting, but can also be a little daunting, as no matter how well prepared you are, you can never be quite prepared for everything. However, by the time your baby is 3 months old, you will likely have developed a routine and stopped questioning yourself about every decision you make, and this is the point where you can really relax and enjoy parenthood.
There are significant developments that happen during this period, and you will see your baby’s personality begin to show too, while they will know who you are and begin to explore the world around them. While this article covers the major developments you may expect to see, it is always important to remember that every baby is different, and they all will grow and develop at their own pace.


It won’t be until around 6 months of age that your baby can be weaned onto solid foods, so right now they will still rely on milk for their meals. The period around 3 months is when most babies enjoy a growth spurt, so tend to consume more milk that they would have been doing at 1 month.
They will also have developed a feeding routine now, requiring between 5 and 8 feeds per day.


A baby is still growing and developing fast at 3 months and needs a lot of rest to provide energy for it all. You probably won’t notice a reduction in sleep requirements overall compared to when they were a newborn. Usually that means somewhere between 14 and 16 hours a day, which is a slight reduction from the first month, but the real difference is in sleep patterns.
Now your baby will most likely be capable of sleeping for at least 5 hours uninterrupted at night, but if your child doesn’t, don’t worry. Some babies simply need more frequent feeds to supply the energy for all that growth. In general, you can expect your baby to require 3 to 5 hours of naps during the day, and then evening and night time sleeping with feeds as required.

Movement and Strength

By the time a baby reaches 3 months, they will have neck and core muscle control, meaning they can lift and support their own heads. If you prop the baby up and support their shoulders in a sitting position, such as in a car seat, the baby can now hold their head up and look around. When you put your baby on their tummy, they can lift their heads, although not for too long, they get tired quickly still at this point.
The baby will have learned how to control limbs now, which means changing can be a challenge as the baby knows how to kick, both with single legs and even both at once. They also start exploring their own bodies here too, and you will see them bringing their hands in front of chests and faces a lot, as they learn how fingers move and so on.
Your baby will start to rock themselves too, both side to side and backwards and forwards, the precursor to crawling, and if you haven’t already, this is definitely time to put the baby in their crib now.

Vision, Hearing and Awareness

A baby can place things in three dimensions now as their eyesight has developed, although limb control hasn’t kept up, so they are unlikely to be able to reach for things yet. They will intently watch the world around them, a bright toy, your face and so on, and can follow a moving object from side to side in a semi-circle in front of them.
A baby will also recognize more sounds now, such as bathwater being ran, when you are singing in another room, footsteps coming towards the nursery and many more, and they will often react with excitement for the things they like.

With your baby now becoming fully aware of the world around them, they can interact with people in a meaningful way. Eye contact is one of the primary ways they learn faces, but this will be accompanied by smiles and what we often refer to as babytalk, and it is about this time you will enjoy the first sound of your baby laughing.
Babies will still cry if they are annoyed, scared, hungry or upset, so pay attention, they really are telling you that something is wrong.
Social Development

Your baby will be more interested in any visitors, and will stare into their eyes and become fascinated with new people. But it is also when they begin to learn a number of emotions, crying when unhappy for instance, and a new one, laughing when happy.
Play Peekaboo, a little gentle tickling or pulling funny faces and you may get that first laugh at this point in their development.


Now you are beginning to see the first signs of personality, as well as your baby becoming more curious, both about their own arms and legs as well as the people they meet and the world around them.
This is a magical time in the development of your child, where you get to see them develop at a faster pace than ever, where they become more aware of their surroundings and engage with you more.
