Why There's No Single "Right" Age
The CDC's "Learn the Signs. Act Early." checklists (revised in 2022 with the American Academy of Pediatrics) describe the age by which most children — 75% or more — can do a given skill. That's a prompt to bring something up with your pediatrician if your baby hasn't gotten there yet, not a hard deadline every baby must hit on the dot.
The table below combines those CDC checklist ages with typical ranges described by the AAP's healthychildren.org, with the source named for each row. If your baby falls within a window, that's ordinary variation. If they're well outside one — especially across more than one milestone — that's worth a conversation at your next well-baby visit, not a reason to worry alone.

Motor Milestones by Month: The Table
| Milestone | Typical age | Source |
|---|---|---|
| Holds head steady without support (when held upright) | by 4 months | CDC |
| Pushes up onto elbows/forearms during tummy time | by 4 months | CDC |
| Rolls from tummy to back | by 6 months (see our full rolling guide) | CDC |
| Sits without support | by 9 months | CDC |
| Crawls on hands and knees (or another mobile style) | usually 7–10 months; normal range about 6–12 months | AAP / healthychildren.org |
| Pulls up to stand | by 12 months (AAP: often begins around 8 months) | CDC / AAP |
| Cruises, walking while holding on to furniture | by 12 months | CDC / AAP |
| Pincer grasp (thumb and index finger) | typically develops around 9 months; CDC checklist expects it by 12 months | AAP / CDC |
| Takes a few steps alone | by 15 months | CDC |
| Walks without holding on to anyone or anything | by 18 months (AAP: first steps often around 1st birthday) | CDC / AAP |

Rolling, Crawling and Walking: Full Guides
Three milestones from the table above are searched often enough on their own that we cover them in depth in dedicated guides:
- Everything on rolling — typical timing, how to encourage it, and what to do if your baby rolls onto their tummy during sleep: Baby Rolling Over.
- Everything on crawling — crawling styles, encouragement, babyproofing: Baby Crawling Guide.
- The strength work behind all of the above starts with tummy time: Tummy Time Guide.
The first meaningful word tends to land in a similar window to first independent steps, but language milestones are their own topic — see our language development guide.
When to Talk to Your Pediatrician
Use the ranges above as a guide, not a deadline. Bring it up at your well-baby visit if:
- A milestone is significantly outside the typical window listed above
- Your baby consistently favors one side of the body over the other
- A skill they previously had seems to disappear — regression is always worth mentioning
- There's no independent movement of any kind — rolling, scooting, crawling — by 12 months

Frequently Asked Questions
When does a baby sit up without help?
The CDC's "Learn the Signs. Act Early." checklist lists "sits without support" as a skill most babies (75% or more) have by 9 months, alongside "gets to a sitting position by herself." Many babies can sit briefly with their hands down for balance a bit earlier, around 6 to 8 months, according to the American Academy of Pediatrics.
When do babies start crawling?
Classic hands-and-knees crawling is, per the AAP's healthychildren.org, "a skill usually mastered between seven and ten months," though the full normal range runs from about 6 to 12 months — and some babies skip hands-and-knees crawling entirely. See our full baby crawling guide for the different crawling styles.
When do babies pull up to stand and cruise along furniture?
The CDC's 1-year checklist lists "pulls up to stand" and "walks, holding on to furniture" (cruising) as skills most babies have by 12 months. The AAP notes babies often start pulling themselves to standing "every chance she gets" from around 8 months, and begin cruising once they feel secure standing.
When do babies take their first steps and walk on their own?
According to the AAP, "many babies' first steps are taken around their first birthday, although it's normal for children to start walking earlier or later." The CDC's checklists track this in two stages: "takes a few steps on his own" by 15 months, and "walks without holding on to anyone or anything" by 18 months.
What is the pincer grasp and when does it develop?
The pincer grasp — picking up small objects between the thumb and index finger — typically develops around 9 months, per the AAP's healthychildren.org ("your baby won't develop the pincer grasp with index finger and thumb until about nine months old"). The CDC's 1-year checklist lists "picks things up between thumb and pointer finger, like small bits of food" as a skill most babies have by 12 months.
My baby hasn't reached a milestone in the age range above. Should I worry?
Not automatically. CDC checklists describe the age by which most children (75% or more) can do something — they're a prompt to bring it up with your pediatrician, not a diagnostic deadline. Being outside the typical window is a reason for a conversation at your next well-baby visit, especially if several milestones are delayed together, not a reason to panic on its own.
