Baby Developmental Milestones: By 7 Months
Rolls both ways -- front to back and back to front
During tummy time, your baby will start to push up, lift her chest, and rock from side to side. When she's strong enough, that rocking will send her rolling over. Many babies flip from front to back first and roll both ways by 7 months. Set up an area where she can rock and roll safely.
Can sit up using hands for support and then without hands
Once your baby can lift his chest while on his tummy, help him learn to sit. Support his back with your hands or pillows. At first, he'll lean forward on his hands to balance. Then, look -- no hands! He'll sit by himself, though it will be a while before your baby can actually sit down on his own.
Picks objects up with "raking" grasp and passes them from hand to hand
Your baby is "raking" things up with her hand. Give her toys with sounds and textures that she can pass from one hand to the other, turn around, and shake. This is her way of bringing the world closer! She'll put everything she grabs into her mouth, so make sure choking hazards are out of reach.
Develops full-color vision and distant vision matures
By this age, your baby can see a full range of colors and shades. Show him colorful toys and books with big, brightly colored pictures. He will probably grab, hold, chew, and drool on books, so make sure they're sturdy vinyl, cloth, or board books.
Responds to own name and begins to respond to "no"
Your baby knows her name and is starting to understand when you say "No." When she's heading for trouble or danger, calmly tell her, "No." Then move her or distract her with another activity. Remember that she's too young to remember "no" for long, so protect her by keeping temptation out of reach.
Uses voice to express emotions and can tell your emotions by tone of voice
Babies this age are babblers. You may not understand what your baby is trying to say, but you probably can figure out from his noises and tone when he's happy or unhappy. Your baby can also tell emotions like displeasure or praise by the sounds you make and the tone of your voice.
