Dhs youngest sister is 14 and lives with his mum, in the October half term mil is going on holiday with her partner and has asked us to have sil. Not a problem but we have said we can't afford the extra costs etc so she will need to give us a contribution, she has offered £50 which will cover her food costs and extra electric, gas etc for the 9 days just.
In that week it's also our dds birthday and we have planned to go to a localish family attraction park which costs about £25 each (not dd as she's under 3). We have set that money aside as we are on a very low income and have to budget things carefully. We explained we will be doing this to mil and would she be able to pay for sil to come as we can't stretch to another £25 easily.
She has said she can't afford to do that.
So our options are:
A)change our plans and not go
B) find the extra £25 ourselves
C) leave sil at home (which seems really mean!)
D) say tough, we won't be able to have her for the week then.
Aibu to think if mil can afford to go on holiday, she can afford to pay £25!
