8-10 Month Sleep Regression: Separation Anxiety | Parenting Hub
A second wave of unsettled sleep around 8–10 months is usually about separation anxiety and big developmental leaps. Here's what helps.
Sleep often gets harder again around 8–10 months. It's developmental — separation anxiety, crawling, pulling to stand — not something you've done wrong.
Why it happens
- Separation anxiety peaks 8–10 months — baby now knows you exist when out of sight
- Big motor leaps: crawling, pulling up, standing
- Often a nap transition (3 → 2 naps)
- First words and gestures developing
What helps
- Extra connection in the day — short, focused 1:1 play
- Same calm bedtime routine, no big changes
- Stay present at bedtime — pat, shush, hand on chest
- Practise pulling up and getting down in the cot during the day so baby can settle if they get stuck standing
- Comfort object (small lovey) from 12 months once safe
How long it lasts
Usually 2–6 weeks. Hold the basics — wake windows, environment, routine — and it passes.
When to seek help
- High fever, ear pain, refusing feeds — rule out illness
- New head banging, very prolonged inconsolable crying — see GP
- Sudden severe sleep change after a fall or knock
Common questions
Should I bring back night feeds?
Comfort and feed if you'd like — short term. If you've already night-weaned, comfort other ways: pat, hand on chest, brief pick-up, then down again.
