    Baby Development: Your 9-Month-Old

    Three-quarters of the way through your baby’s first year and there is hardly a trace of that tiny bundle you brought home from the hospital just nine months ago. Now your baby is a mobile, vocal, and very enterprising adventurer.

    In this portion of WebMD’s month-by-month guide, you’ll discover what baby milestones you can expect your child to achieve when she’s 9 months old.

    Your baby's first year will be full of joys and challenges. WebMD pediatrician Steven Parker, MD, explains what you can expect as your baby grows and develops.

    Ninth Month Baby Milestones: Motor Skills

    At nine months, your baby has likely become an expert crawler. Some babies are such crawling pros they can hold a toy in one hand while they propel themselves using the other hand and their two knees. Some can even crawl up and down stairs with ease. Just make sure you keep the gate closed unless you’re there to supervise the climbing.

    At nine months, babies are also becoming experts at quickly changing position. They can push up to a crawl position, sit back down, and pivot to pick up a toy. Your little one may even be able to pull to a stand, and may soon start cruising around the room while holding onto furniture.

    Although those tiny baby shoes might look enticing on the store shelves, you don’t need to invest in shoes until your baby actually starts to walk or is spending lots of time outdoors. For now, barefoot is best when indoors. Standing and walking in bare feet helps him develop the muscles and tendons in his feet. It’s also easier to grip the floor in bare feet. When it gets cold outside, socks with non-skid bottoms will keep your baby’s feet warm.

    In addition to getting ready for walking, 9-month-old babies are also improving their fine motor skills. With their pincer grasp, they’re able to pick up smaller toys, and they can better coordinate the movement of both hands. These little sleuths will use their newfound motor skills to try to figure out how everything works -- which peg fits in the round hole, how cups fit inside one another, and which end of the toy telephone goes over their ear.
