FirstWeeksYour baby at 37 weeks: pull-up era
Medically-informed · Sources: CDC · Updated June 2026
Furniture becomes gym equipment: pulling to stand commonly starts — along with the famous 8–10-month sleep wobble.
What’s happening
Standing practice, everywhere
Crib rails, couch edges, your legs — everything vertical is a pull-up bar. Wobbling and plopping down are the curriculum.
The 8–10 month sleep dip
Commonly seen: night waking to practice standing (sometimes stuck standing and yelling), separation feelings at bedtime. It's development, not broken sleep habits.
Crib check, again
Mattress to the lowest setting NOW if not already — pull-up plus old mattress height equals an escape attempt.
What to do
- Lower the crib mattress today
- Practice controlled sit-downs: guide hips down so baby learns the exit move
- Keep bedtime routine identical through the wobble — boring consistency wins
When to check in
Standing stuck and crying at 2 AM: calmly lay back down once, minimal fuss, repeat — it passes with practice.
