PIL and their family live on the continent. SIL, who has a three year old and twin one year olds is fortunate to be able to rely on regular free childcare from her mother so that she can work part time. MIL also helps out on weekends so that SIL can play sport/go shopping, and she has had the kids for several weekends so that SIL and her dp can go away together.
Now I don't begrudge this at all - I think SIL is very lucky and I know that she needs a lot of help and breaks because toddler twins and a preschooler is hard work.
We have no free childcare on tap here. My mother is dead and my remaining family dislike children. We have been invited to a wedding of close friends in May, in a location five hours drive away. Our kids are not invited. We asked MIL if her and FIL could come over that weekend to look after the kids, so we can go to the wedding. MIL says it's not convenient because she's planning a weekend away with her friends that month (dates not fixed).
AIBU to think it's a bit unfair that her daughter gets so much childcare and yet when we ask, she can't ringfence one weekend for us? She said if her weekend away ends up happening on different dates, they'll try and help out, but we'd have to drive back from the wedding first thing the next morning so they could get home because FIL has a social engagement on the Monday.
I've been made to feel like I'm asking an awful lot of them. Dh doesn't like putting anyone out and says I should just go to the wedding while he stays at home with the kids. AIBU?
