2 kids aged 8 & 6. They don't do loads of after school clubs so are generally at home from 3.30 with us.
Dp and I both work FT around the kids (so make up hours once they're in bed etc). This isn't every night but sometimes will have to work until 12pm / 1am (maybe once every 2 weeks).
By the time the kids are getting ready for bed at 7 I could totally pass out with them. And at 8pm I'm ready for bed myself, unless I have to work or go out in which case I'll generally get a second wind.
Does anyone else feel like this?
