I think it depends on the amount the other parent/partner works as well. My partner was doing a load of overtime, doing about 60 hours a week, so I didn’t mind doing the housework then (well, I minded as I hate it, haha! but I knew it was only fair I had to do it myself at that point). But when she’s only working normal 37 hour weeks, it frustrates me. She made a comment the other week about how it was her week off so she didn’t have to do anything. I asked when it was my week off and she said every week was my week off. Hmm, given that I’m still breastfeeding and up several times a night for it, that didn’t go down too well!
