Before you have a baby of your own, you may roll your eyes at other parents who squeal in delight over their child rolling over or laugh to yourself when they post a picture of them lifting their head. But when you become a parent yourself, you quickly realize why these little moments are so monumental. After a few weeks at home, you will begin to notice your baby doing little things, and if you’re like me, you start checking off those milestones as your baby’s very first accomplishments.

Before you have a baby of your own, you may roll your eyes at other parents who squeal in delight over their child rolling over or laugh to yourself when they post a picture of them lifting their head. But when you become a parent yourself, you quickly realize why these little moments are so monumental. After a few weeks at home, you will begin to notice your baby doing little things, and if you’re like me, you start checking off those milestones as your baby’s very first accomplishments.

At each visit to your pediatrician, they may ask a few questions to see if your child is making their milestones at the appropriate time. For some parents, these questions can lead to anxiety or stress that their child isn’t keeping up, but don’t fret—babies do things on their own time, and if your child isn’t quite crawling at the average age or babbling when others his age are, it’s totally fine. Any concerns about missed milestones should be discussed with your doctor. If they aren’t worried, you shouldn’t be either!

While a lift of the head is exciting, it’s around 9-12 months old that things really start to progress. For my daughter, this was the time when everything changed—she became mobile, began to express wants and needs, and before I knew it, my tiny baby had become her own person.

If you want to track your baby’s 9-12 months old milestones on your own, there are many apps, including one from the CDC that allows you to not only keep track but add images and videos as well. Here are the things you need to be keeping an eye out for.
