I cook their dinner (home cooked, not ready meals) but they sort themselves out with lunch and breakfast and multiple snacks as and when they want it.
If I'm making my lunch then I'll offer to make theirs, especially if they are doing schoolwork but less so if they are on the xbox.
I always cook and nearly always wash up before/after. If they are working on school work then I always do it but at weekends I expect them to wash up after dinner or do some other job while I do such as hanging laundry out/bringing it in or doing a tidy round in the lounge.
Should I be making their breakfast and/or lunch? Should they be doing the clearing up after dinner?
I sometimes feel like I expect too much and other times not enough.
YABU - you should be doing more
