Babies go through many changes during their first year of life. Some changes are obvious for all to see such as hair growth and body size, while others, including emotional development, are not. Each baby will develop emotional and social skills at her own pace, but some guidelines do exist to help you know what to expect.
Up to Three Months
The first few months of your baby's life start to lay the foundation for his emotional development. You will notice little milestones such as making eye contact, crying for help when he needs you, responding to your voice and smiling in response to people's faces. Anger may also be evident when he doesn't get his way or is uncomfortable. Much of the baby's emotion is subtle in the first three months, as he adjusts to life on the outside.
Four to Six Months
During months four to six, your baby will begin to show more noticeable emotions by crying when her play is disrupted or a toy is taken away, and laughing when she finds something amusing. She'll also be able to differentiate between family members and strangers, and react when she hears her own name. The laughter and crying in response to the situation won't be consistent, and may vary from one day to the next.
Seven to Nine Months
Between the seventh and ninth month, your baby will begin to show frustration when he can't do something he wants to do. The word "no" is understood, but not always met with a warm reception. His focus will increase, and he should start mimicking sounds he hears from adults. He may even recognize and smile at his own image in a mirror.
Ten Months to One Year
Separation anxiety to some degree may set in once the tenth month rolls around. Some babies are not affected, especially if she has spent time with many different people. You will notice different moods from your baby in response to situations. She will begin to seek out approval from parents or other family members and avoid disapproval. Her sense of humor will start to become more evident and tantrums are not uncommon.
