Hi everyone our nearly three year old has on majority been a good sleeper. She wakes around 7/8 in the morning , doesn’t nap in the day. The odd time falls asleep in the car but we limit this to 20 minutes . Then goes up to bed around 7 and used to sleep through the night. A few weeks ago she began waking between 12 and two and is up for hours on end. It’s like once she’s awake she’s wide awake. Things went back to normal for a few days now she’s back at being awake every night for hours again. In her bed she has one or two comforters . I’ve tried everything to stop her waking in the night but I’m at a loss what to do next .
