I don't, as a childminder I serve up 40 odd meals a week. I cook in the evenings for kids and DP. Every night.
If he was home, I'd arrive at lunchtime with 3 toddlers and never ever was a sandwich made for me, but DP would come down from his office and say 'what are you doing for lunch?'
If he was out for the morning, coming home, 'I didn't eat any breakfast and whining at me what can he eat'.
Constant update all day what he has / hasn't eaten.
I don't actually give a fuck, as I'm not his Mother.
