10 month old sleep issues - help
​
My daughter is 10 months. We've coslept in her room since 5 months, cot for day naps since 7 months. She was easy to settle until about 2 months ago.
**Current situation:**
- Wake windows: 2-2.5 / 3 /4.5 hrs. Morning nap ~30 min, afternoon ~90 min
- Breastfed at night, bottle during the day (Dad on parental leave), good solids 3x per day.
- Night sleep once she's down with me is okay — 3–4 guided feeds, otherwise settled
- Pretty sure her sleep association is me as primary attachment person
**The problems:**
- Dad cannot settle her at night at all — even if she falls asleep on him she won't transfer to the cot
- She ends up on me in the living room until I go to bed, and lately that's not even working
- Sometimes second wind 8–9:30pm after waking crying at first sleep cycle
- Day naps with Dad hit and miss
- Lots of flailing, head butting, rolling before settling — motor activation from milestones?
**Context:**
- Cracked crawling 14 days ago, almost pulling to stand
- Back to back illness recently
- 5 year old needs mum at bedtime simultaneously 🫠
- Zero evening time as a couple since born, exhausted
**Questions:** Anything we can do to help Dad settle her at night, or do we ride out the regression? Any tips for reducing her dependence on me for the first part of the night?
Thank you!
