My 2.5 yo DD has never been a great sleeper but has recently started waking every night at 4am. She goes to nursery 4 days and our routine was 9-7 sleep for getting up on time with a 45 min nap at nursery. She’s now awake 4-5am going back to sleep and not waking up until after 8am!! Still snoring beside me at 0830 (it’s my day off). I bring her into bed with us so we can all get more sleep. I didn’t mind this occasionally but it’s getting tiring doing it every night. Is this a phase? How do I get her to sleep through again???
