Your baby may soon start walking, if he/she has not already. He/she will become more mobile and his/her interest in noisy activities will probably increase.

His/her weight has likely tripled since birth. But now his/her weight gain will start to slow down as his/her activity level will increase.
As he/she is growing up, he/she may be interested in more energetic games to strengthen his/her arms and legs. he/she may consider it fun to push, throw and knock everything down. He/she may like games where he/she can put blocks in containers and then throw them out.
His/her motor skills will be well developed by this time. He/she should be standing alone, and may even have taken his/her first solo steps. he/she is able to do few things pretty well, like eating with his/her fingers and turning pages of story books.
By this time, your baby should be sleeping less during the day and more at night. He/she may be taking his/her afternoon nap regularly but his/her morning sleep may be a thing of past.
At 12 months, you can make the transition from breast milk or formula to cow’s milk.
Your baby’s separation anxiety is probably growing because he/she depends on you. He/she might cry for a while, but his/her tears will be gone after you are out of sight.
Your baby is learning his/her language imitating his/her parents. he/she will be able to understand what people are saying to her. he/she may start throwing tantrums when you say “no”. Start rewarding his/her good behaviours and try to be firm when he/she doesn’t behave well.
It is probably the time to buy his/her first pair of baby shoes. He/she will soon walk on his/her own. Make sure his/her shoes are comfortable enough. You may have to buy new shoes for him/her again after two or three months as your baby’s feet will continue to grow.
