Your child will likely reach this baby development milestone soon after he's able to sit well without support (probably by the time he's 6 or 7 months old). Crawling is your baby's first method of getting around efficiently on his own.
Cutting teeth isn't one of those baby development milestones your child reaches all at once. Transitioning from that gummy grin to a mouthful of gleaming teeth is a rite of passage that can take your little one as long as three years to complete.
Your child will probably reach this baby development milestone between the ages of 4 and 7 months. Sitting independently gives your baby a new perspective on the world.
When it comes to baby development milestones, your baby's first steps can't be beat. One day he's holding onto the couch and the next he's tottering hesitantly into your waiting arms. Your child's first steps are his first major move toward independence.
