A baby grows at an astounding rate. In just 12 months, your baby can transform from crying new-born to a toddler that can crawl on its own, stand on its legs with support or even say some words. Every month, there are major development milestones that transform your baby. New parents can be worried about their baby’s development and what to expect next. Each baby takes its own time to develop, for example, some may start walking early while some may walk late. Don’t worry, this baby development guide will help you month by month about your baby’s physical and mental development.

Baby Development Month by Month



Month 1

This is the beginning of your parenthood. Babies at this stage will mostly cry all the time. Don’t worry, it will eventually subside with development. Just cuddle them and make them comfortable. Physically they will grow from 700 to 900 grams of weight and can grow from 2.5 to 4 cm. Their head will grow in size. They will start recognizing your voice at this age. Spend as much time as possible with your baby. They like hearing your voice, so sing them a song or lullaby. But they can be frightened by any loud noise and start crying which is normal.

Month 2

At this stage, your baby will grow taller and his weight will increase. He will be stronger due to the development of his muscles. He will be able to hold small objects in his hands. They will sleep for extended periods and mostly be awake during the day but sleeping patterns can vary widely. Again, spending time with your baby is very important. Keep smiling, singing and reading so that they feel comfortable and safe.

Month 3

Your baby will put on more weight and will become round and chubby. They will start responding to your voice and sounds around them. Their sense of touch will also improve and can hold objects in their hand very well. This is an important stage as communication is concerned. Read them different baby books so they can recognize your voice and know how to converse. Massage your baby mostly after a bath. Most importantly, most babies can sleep through continuously and not wake up in the middle of the night.

Month 4

Your baby will grow more. Their muscles and bones will become stronger and some can roll over on their own or even sit upright. They also start to show different emotions and can show happiness, frustration or anger. Most importantly, their mouth becomes ready for solid foods but not completely. Their sense of touch and vision will improve greatly and will start to associate their vision with hearing. Most of the frequent crying will subside by now.

Month 5

At this stage, your baby can roll over quite easily, from back to front and vice versa. He can also sit upright without any support for some time. Since their neck muscles have become stronger, they can lift their head up. They pick up small objects in their vicinity and can hold it. They can also tell you by actions what they want, for example, they can put their arms in their air to pick them up. They also start responding to different sounds. So, read to them different books, speak and sing with them.

Month 6

The most important thing at this stage is to prepare the baby for eating solid foods. First, give them semi-solid foods like mashed potatoes so they can learn how to eat. Your baby’s hand coordination will improve. Now they can sit upright without support for a longer time and can also use their legs to kick and adjust their position. They start producing different sounds like “baba” or “gaga”. Your baby can understand some facial expressions and also understand the tone of your voice.

Month 7

By now most of the babies are ready to eat solid food but not completely. Don’t give them hard foods that are difficult to swallow. But the major part of their diet is still milk. At this stage, some babies will have their first teeth start to come out of their jaw. They will be much better at sitting upright without support. Some may start crawling. So this is the right time to start baby-proofing your house. Your baby’s hand coordination will also improve, they may be able to pick objects with their fingers and pass on the objects from one hand to another.

Month 8

At this stage, your baby’s muscles will grow stronger, they start crawling and some can stand on their legs with support. So you have to take care of them and secure the furniture so it does not fall on them. Their eyesight will improve further and start pointing at things and objects which they want. Most of the babies will start to suffer from Separation anxiety – they will cry and not feel comfortable when you are not close to them.

Month 9

Most of the babies at this stage can stand up on their feet with support and some can even move around while holding on to support. Your baby will love playing with toys. Give him different kinds of toys to play with. He will pick them, bang them, throw them which is normal. They will also develop emotionally. They can sometimes refuse you which is also normal. They start understanding different words and repeat them.

Month 10

Your baby will be well mobile now and can stand on their feet and sit from standing position. Most of the separation anxiety will subside by now and they may be comfortable with strangers. Your baby’s physical development will slow down a bit. They may be more aware of their environment with the development of their senses. Some babies can even utter their first word at this stage while some babies require 12 months to do that.

Month 11

Most of the babies can stand on their legs with support and some babies can even have their first steps but for most of them, it will require a few more months. Their dependence on breastfeeding will decrease gradually and they will start eating foods other than milk by their own fingers. Some can even lift a cup and drink from it. Your baby will move around a lot in the house, so your house should be baby-proofed by now. Light bruises from bumps are common at this stage. You can help your baby practice walking slowly.

Month 12

Your 12-month-old baby’s weight will be 3 times that of the weight at birth. By this time, your baby’s diet plan should include some amount of cow’s milk, some vegetables, and fruits. Their hand coordination will improve and some can even hold a spoon and feed themselves. They will utter more words and their vocabulary will improve. They will develop physically, mentally and emotionally and they will slowly transform from a baby to a toddler.

A baby’s development in the first 12 months is very fast. You will not recognize when your baby will develop from a new-born always sleeping and crying to a toddler who smiles, laughs, plays and walks by himself. Some babies develop fast while some develop slowly. Don’t worry if your baby is slow to show signs of development, each baby develops at his own pace so give him time to develop and explore this beautiful world. I hope this Baby Development Guide will help you to become a better parent.
