I have so sick battling with my (just) 12 year old dd over bedtime.
Up till recently her lights out time was supposed to be 9.15pm but it hardly ever was as she faffs around for ages. Constantly nagging her to get ready for bed etc which doesn't make for a peaceful evening for me. Her beef with me was I treat her like a baby, I'm always nagging, she doesn't need as much sleep as I think etc.
So I compromised with her and gave her an extra 15 mins, so 9.30pm bedtime and she should stick to it. This was a few weeks ago and again it's been creeping closer to 10pm each night.
She leaves for school around 7.35/7.40am but likes to be up early so not to rush (6.30am ish).
I'm not sure whether to still insist on this bedtime, or give her a bit more autonomy and allow her a bit of leeway. Plus, if she doesn't go to bed on time, I can't think of an appropriate punishment other than phone removal which doesn't seem right.
