The last development stage in baby’s first year is quite a transition. They aren’t an infant anymore, and they might look and act more like a toddler. But they are still a baby in many ways. They are 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 their 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 they want 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 their first steps. This usually happens right around one year, but it can vary greatly.

What should you do if you think your baby is not meeting growth or developmental milestones, when they 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 themselves or says their first words that is important; it’s that they are moving forward in their 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.’”

This table shows common developmental milestones that babies reach each month during their first year, in four major categories. Keep in mind that all babies are different and every baby grows at their own pace. There's no precise time that most of these skills first appear. If your child hasn’t reached a milestone by the month it is listed on this chart, it is usually a perfectly normal variation in child development. Watch for progress, not deadlines.
