For the past few months my 7 year old daughter has basically stopped sleeping. She will go to bed as usual around 7.30/8 but lie there for hours unable to sleep. When she does sleep she wakes up frequently and she's becoming exhausted. We've tried cutting out screens in the evening, using audible to play a book, using lavender cream and spray, letting her read for a short time plus other stuff but nothing seems to work. Husband wants to take her to the Dr but unsure what they'd do? Any ideas?
