If I see one more person referring to their other half as 'babysitting' or 'looking after' their child I think I may let out a little rage noise! He's the Child's father. His role is that of a parent. If you're poorly you shouldn't be thanking him for stepping in to look after said child, he should be doing it because it's what he signed up for when he got you pregnant!
I know I'm going to get flamed for this but it's been annoying me for a while now
