DD slept really well up until around 10 months ago and then has been unable to sleep through the night. She turns 3yo 5 months ago. I am honestly at my whits end. I feel like there must be something underlying that's wrong for her to go from a gold star sleeper to waking sometimes 3-4 times a night. Could there be a reason for it other than sleep regression? I feel like I've exhausted every avenue of thought and tried my best to help with nightmares, fears etc with nightlights etc. Last night she peed 4 times in 6 hours. I took her to the gp and they are checking her glucose levels as she is drinking a normal amount and I only give her water, on occasion apple juice but not regularly. I also dont offer drinks 2 hours before bed unless she asks. This morning she was awake at 6am and then didn't go to sleep tonight until 9.45pm. I am so frustrated and also worried out of my mind that something is the matter with her and she can't tell me. Anyone have any thoughts?
