Growth

  • Your 9-month-old baby boy is constantly trying to move around. When he’s not crawling about while holding onto furniture (this is called cruising), he’s probably trying to push himself up the stairs. He’s also gotten so good at changing positions by himself: he can sit himself down, position himself on all fours, and momentarily stand without support.

Development

  • Your 9-month-old baby boy can start stringing together vowel and consonant sounds, which may resemble words. Be patient, however: it may still take him a while to correlate “mama” or “dada” with what they actually mean.

  • Your baby may start better understanding your body language, tone, and instructions, and perhaps even begin imitating sounds.

  • His grasp of language is developing as well. For instance, if you ask him where his rattle is, he might pick up a rattle.

  • As your 9-month-old baby’s memory and awareness start improving, he may also begin experiencing separation and stranger anxiety. For example, he may start crying whenever you take away his favorite toy or his aunt comes over for a visit.

Some tips

  • Since your 9-month-old baby is raring to move around, provide him all the opportunities to do so. Just make sure you’re around to watch over him. Since he’s not able to recognize potential dangers, start childproofing your home to keep him safe.

  • Your baby is never too young for rules and limits. By this time, he probably understands the word “no” so use it when he’s about to do something naughty or bad for him.
