Baby Development: Seven to Nine Months

During the second half of this year, your little one becomes a baby on the go. After learning that he can get somewhere by rolling over, he’ll spend the next few months figuring out how to move forward or backward. If you haven’t baby-proofed yet, better get on it!

  • During this time period, your baby may:
  • Start to crawl. This can include scooting (propelling around on his bottom) or “army crawling” (dragging himself on his tummy by arms and legs), as well as standard crawling on hands and knees. Some babies never crawl, moving directly to from scooting to walking.
  • Sit without support.
  • Respond to familiar words like his name. He may also respond to “No” by briefly stopping and looking at you, and may start babbling "Mama" and "Dada."
  • Clap and play games such as patty-cake and peekaboo.
  • Learn to pull up to a standing position.

Baby Development: 10 to 12 Months

The last development stage in baby’s first year is quite a transition. She isn’t an infant anymore, and she might look and act more like a toddler. But she’s still a baby in many ways. She’s learning to:

  • Begin feeding herself. Babies at this developmental stage master the “pincer grasp“ -- meaning they can hold small objects such as O-shaped cereal between their thumb and forefinger.
  • Cruise, or move around the room on her feet while holding onto the furniture.
  • Say one or two words, and "Mama" and "Dada" become specific name for parents. The average is about three spoken words by the first birthday, but the range on this is enormous.
  • Point at objects she wants in order to get your attention.
  • Begin “pretend play” by copying you or using objects correctly, such as pretending to talk on the phone. 
  • Take her first steps. This usually happens right around one year, but it can vary greatly.

 

Your Baby’s Development: When to Talk to a Pediatrician

What should you do if you think your baby is not meeting growth or developmental milestones, when he should? First, says Shu, trust your instincts. “If you really feel like something’s wrong, then talk to your doctor about it because if there is a problem, we want to catch it as soon as we can," she says. "Early intervention is best, and you know your child better than anyone.”

Remember, however, that it is not exactly when your baby sits up by himself or says his first words that is important; it’s that he’s moving forward in his development. “Don’t look at the time as much as the progression, and see that your child is changing and growing,” says Shu. “It’s not a race. Nobody’s going to ask on a college application when your child first walked or said ‘da-da.’”
