For over 2 Months my DD4 has normally gone to sleep at 7pm but now wakes up fully within 2-3 hours and wants to be up for hours. She is not tired and then I have to go to bed to get her to bed. I'm exhausted and I have no evening downtime because of this. HELP!!! She used to go to sleep at 7 and sleep all the way through to 7.30pm - big routine and sleep training when she was still in a cot. How do I get her sleeping properly again?
