The layer of stabilizing back muscles plays an important role in a baby’s developing ability to sit and move around independently.
Push-ups
Babies begin to build strength in their stabilizing muscles from about three months old. They lie on their tummies and lift their arms in the air to flex these muscles.
Sitting up
By nine months old, most babies have developed their stabilizing muscles enough to be able to sit up on their own.
First steps
At around a year old, a baby can stand on her feet and start to walk without help. Stabilizing muscles are still gaining strength, so early attempts can be wobbly.
