DP's Mum always makes us feel guilty if we don't go visit her at least once a week. She is in her 70's, but DP and I have 2 DD's under 3, and both work full time, so it feels like getting out to do anything is a struggle at the minute. DP has 3 other siblings, and all make sure to phone at least once a week, but even if we do, MIL gets annoyed and makes us feel guilty because we didn't visit. AIBU to just take one weekend a month to get on top of housework, go shopping etc and not go see MIL with the kids? Other sibling visit when they can, as do grandkids with great-grandkids, so it's not like she doesn't get to see anyone.
