Hi,my 20month old daughter Sofia has always been a poor sleeper. The current situation is she co-sleeps on a floor mattress with her mum. She goes down fairly easily by laying with her and hand holding. We have a very strict nap schedule and bed time routine. She naps from 12:30- 2:15 (1hour 45mins). Then goes to bed at 7:45. She has a snack and milk before bed, and a magnesium spray massage before stories and her dummy is given. However, she now wakes every 3 hours, often shorter. It takes at least 30mins, up to 3 hours to get her back to sleep by laying with her. She insists on holding our hand during this time while fidgeting non stop. Would any kind of sleep training work here? Any recommendations? How long would it take? We are both willing to take time off work and commit to it, but I guess we’re skeptical it would work. My partner is suffering terribly with sleep deprivation and our mental health and work is affected badly. Totally at our wits end.
