DD is ten and frequently goes through phases of several nights, or even weeks, of being difficult at bedtime. She goes to bed between 9.15-9.45 and gets up at 8 so she's definitely not going to bed too early and ten hours is enough so I don't think it's too late, either. She has tons of exercise and not much sugar.
I tuck her in and we chat for 10-15 minutes. On a good night, she then goes to sleep. On a bad night she'll be up ten minutes later saying she's too hot/too cold/not tired/something hurts. I'll reiterate the need for sleep but she'll be up again ten minutes later and will start whimpering and wailing, and eventually screaming and crying and waking her siblings.
She gets plenty of one on one time and I wouldn't mind if she read quietly for a bit but a) she mostly won't and b) if she stays up any later she's a nightmare to get up in the morning and extremely moody. She doesn't have any technology so I can't remove that, stopping activities punishes me too as it's wasting my money. I've stopped her having sleepovers until she can go to bed well consistently but it still keeps happening.
Last night she was in bed for 9.45 yet up and down screaming and crying until 11.30. The next day she refuses to talk about it. Does anyone else have an older child that struggles like this or any suggestions on how to stop this?
