8 Month Baby Sleep: Regression, Standing in Crib and Schedule

The 8-Month Regression: 3 Causes at Once

Motor leap. Brain rehearses crawling, pulling to stand during sleep.
Separation anxiety peak. Baby understands you can leave but doesn't understand you'll return.
Cognitive leap. Cause-and-effect, object permanence — massive brain development.

Standing in Crib — The Classic 8-Month Problem

Baby pulls to stand but can't get back down. Solution: practice sit-from-standing during play, 10–15 times daily. Within 1–2 weeks, the skill is automatic and nighttime standing stops.

Don't drop to 1 nap at 8 months. If one nap fails — it's regression, not readiness. Average transition age: 14–18 months.

FAQ

How long does the 8-month regression last?

Average 3–6 weeks. Babies with self-settling skills: 2–3 weeks. Without: can feel much longer.
