Baby Milestones

During the first weeks, a baby does very little besides eating, sleeping, crying and pooping.

But as the weeks go by, you’ll see them learn new skills as they discover the world around them. Developmental milestones are things that most children do at a certain ageHow a child plays, learns, speaks and acts can tell you a lot about how they are developing. 

Every Child is Different 

When it comes to meeting developmental milestones, remember that every child is different and will master skills in their own time. “Milestone timeframes are meant to give parents a general idea of when their baby should gain new skills,” says Sarah Johnson, a clinical physical therapist at Riley Children’s Health. “Each child is different and will develop at his or her own rate. There are a variety of factors that can affect development that are not necessarily red flags.’” 

It’s also normal for skills to ebb and flow. “It is normal for skills to emerge and then have a slight regression, only to appear again later,” Johnson says. 

In general, however, you want to see your child making progress over time. “Milestones should follow a general progression,” Johnson says, because skills build on each other.
