Appearance
Sitting, crawling, pulling up, cruising
Mobility changes the safety picture faster than almost anything else in the first year. Once a baby can sit, scoot, crawl, pull up, or cruise, the hazard list changes from “things they can reach” to “things they can now move toward with intent” 12.
What these skills usually mean
The exact order does not matter as much as the fact that the baby is gaining ways to explore the room. CDC milestone checklists note that by this age babies are commonly moving, getting up on hands and knees, and interacting with objects more deliberately 14.
What to change at home
Move hazards higher, anchor furniture, keep choking-sized objects out of reach, and check cords, stairs, windows, and low shelves. The floor itself becomes the main play space, so it needs to be treated like a shared environment rather than a clean afterthought 23.
What the baby needs
Lots of supervised floor time, space to practice, and enough repetition to strengthen balance and coordination. The goal is not to rush a movement milestone; it is to make the next movement safer 23.
When to bring it up
Loss of a skill, marked asymmetry, or stiff or floppy movement patterns should be brought up at a visit. A baby who is moving very differently from expected deserves an actual conversation, not a wait-and-see shrug 14.
