Nine-Month-Old Developmental Milestones

Babies develop at different rates, but by the end of your baby's ninth month, he will probably:

• Pull himself up to a standing position.
• Walk while holding on to furniture.
• Grab objects with his thumb and index finger — the "pincer grasp."
• Say "mama," but only as a sound, not a name.
• Wave "bye-bye."
• Understand "no."
• Actively participate in games such as "pat-a-cake" and "peekaboo."
