We're having problems with our daughters bedtime. She goes to bed and messes around, when we give her consequences (no iPad, no chocolate day, no TV we've tried everything that we know she likes in the hope it would help). We speak to her 3-4 times most nights. Our son who is 2 goes to sleep better than her (daughter is 9). She goes to bed at 7:30 to read then to sleep at 8. If she has a later night than that she is grumpy and her attitude gets worse the next day. Which then means she gets told off because of her behaviour the next day.
We have a good bedtime routine in place, it's just once she's in bed.
