As mentioned in another thread I am embarking on the task of improving 4yo dds sleep (going to bed at night on her own, not getting up in the night etc). As my 10yo ds can take hours to go to sleep (presumably he plays up because he knows his sister is faffing around) I thought I'd start fresh and apply exactly the same rules to both of them. So my question is, what is a fair bedtime for a 10yo? I don't want to put him to bed too early, but at the same time he's aaaaaalways tired! Thanks in advance!
