And how do you cope?
DS (4.5) only needs 9 hours sleep. He's consistently gone with about 2 hours less than the books say he should, right from the early months. Behaviourly he seems fine on this - concentration, behaviour and mood seem fine on this amount of sleep. The trouble is I need about 8 hours, so by the time he's in bed (usual.y 9.00 till 6.00 - can't put him to bed any earlier as the thought of being woken before 6 is more than I can handle), there isn't a lot of time to do dishes/laundry/housework etc, and next to no unwinding time for me (and also no grown-up telly, no time to practise musical instruments, no time to catch up with reading from work). I switch between going to bed really early (9.30 ish) and getting enough sleep, or going to bed later (not enough sleep, but I need periods of me-time for my own sanity). Single mum, so no-one to share chores with.
DS is lovely - great fun and v. interesting. But if anyone has some handy hints for how to deal with the inevitable point where he starts needing less sleep than me, please let me know (or even how to generate a bit more time for me).
