Me when someone tells a parent their baby is “behind” because they aren’t walking at exactly 12 months.
Let’s bust this one. ⬇️
MYTH: Babies should hit milestones at the exact same age.
Truth: developmental milestones happen in a range of normal. They are as I like to say, a guideline…not a deadline. The reason we track them isn’t to create a checklist your baby has to nail on a specific date, it’s to give us a window to notice when extra support might be helpful.
For example:
✨Sitting independently ranges from 5–7 months
✨Crawling typically emerges between 7–10 months (and yes, we already talked about whether crawling is even required…go check that post! 👀)
✨Walking typically happens anywhere between 9–15 months
Every baby is wired differently. Temperament, environment, floor time, birth order…it all plays a role.
What I do pay attention to as a pediatric OT is the quality of movement and development, not just whether a milestone happened by a certain date.
Here’s the important balance: busting this myth doesn’t mean dismissing your concerns. If something feels off, trust that instinct. Milestones exist for a reason. They help us identify when a baby might benefit from a little extra support early, and early support is always a good thing. The goal isn’t to ignore development, it’s to stop measuring your baby against an imaginary perfect timeline.
