Up until about 3 weeks ago. DD 4y5m would fall asleep within 10 minutes and be asleep by 8.
It's now taking her ONE HOUR 😭
I've tried making sure her bedroom is dark.
Her bedtime routine has not changed in 3+ years and remains bath, 2 books, lights out and I'll sit and wait for her to sleep.
She's definitely had enough exercise, was at park for 1hr30m after having been to nursery until 12 and out with Granny for lunch, and played in garden for 45+ minutes.
She doesn't watch TV all after lunchtime.
She uses no screens/iPads
She's had her dinner and isn't hungry.
We just read and colour and stuff after dinner.
I've tried moving her bedtime to be later (ie try moving lights out by 20-30-40-50 minutes etc. just pushes falling asleep time by that much (last night asleep at 9:45 of an hour wriggling around, chatting, singing, kicking legs, shouting "I can't sleep!!!!" Etc.
But here she is WIDE FUCKING AWAKE at 9:25 again... She had lights out at 8:20pm.
The problem is she then sleeps solidly for 11-12 hours., and is causing her to sleep in until gone 9am... (Have also woken her up early (partly because of having to leave the house for nursery!) in order to "reset" her sleep time.
Not sure what to do 😭 any suggestions?
