Developmental Milestones: 12 Months: 
What are some of the developmental milestones my child should reach by twelve months of age?

From eight to twelve months of age, your baby will become increasingly mobile, a development that will thrill and challenge both of you. Being able to move from place to place will give your child a delicious sense of power and control—her first real taste of physical independence.

Developmental Health Watch
Each baby develops in his own manner, so it’s impossible to tell exactly when your child will perfect a given skill. Although the developmental milestones listed in this book will give you a general idea of the changes you can expect as your child gets older, don’t be alarmed if his development takes a slightly different course. Alert your pediatrician if your baby displays any of the following signs of possible developmental delay in the eight-to twelve-month age range.

    Does not crawl
    Drags one side of body while crawling (for over one month)
    Cannot stand when supported
    Does not search for objects that are hidden while he watches
    Says no single words (“mama” or “dada”)
    Does not learn to use gestures, such as waving or shaking head
    Does not point to objects or pictures
