FirstWeeksYour baby at 41 weeks: little climber
Medically-informed · Sources: CDC · Updated June 2026
Vertical ambition arrives: stairs, couch cushions, the dishwasher door — everything is Everest, and a growth-hungry stretch commonly rides along.
What’s happening
Stairs enter the chat
Crawling UP stairs commonly starts before any safe way down exists — gates top and bottom stop being optional.
Appetite spike
A pre-10-month hungrier stretch is commonly seen: more solids interest, bigger portions, sometimes a extra milk feed.
Cause-and-effect toys win
Buttons that beep, lids that flip, balls that roll down ramps — baby is testing how the world responds.
What to do
- Install stair gates top AND bottom this week
- Teach backwards-down-the-stairs as the house technique (later, supervised)
- Anchor check: bookcases, dressers, TV — climbing changes the physics
When to check in
Loss of any acquired skill remains an always-call.
