I normally would send DD (8) at 8. Brought it back from 8.30 long ago, but lately that doesn't even seem early enough.
I sent them at 7 on Monday night & they were all asleep by 7.30! They suprised me & didn't wake til 8am! Sent them at 7.30 last night. DD1 was up about 7.30, I still had to wake DD2.
So I think 7 - 7.30 will be bed time around here more permanently now. DH always thought I was slack the nights I sent them early when he was working away. Now he see's exactly why I do it!!
