I am in desperate need of advice! My daughter is 18 months old and seems to be going through sleep regression. She wakes between 1am and 3am and screams for hours. When I go in to check on her she begins to laugh and point at her books as though she wants to play. She thinks it's a game. I made the mistake of reading to her a couple of times when she woke before I learned what sleep regression was. I've tried comforting her, leaving her to cry it out etc.
What did everyone else do at this stage? My wife and I are running on zero and nothing consoles our daughter through the night.
