My sister and BIL have been invited to a wedding in New Zealand just before Christmas - BIL is from there and has been asked to be best man. They have a 6 yo son who is lovely but won't finish school until the day before the wedding and will cost a fortune in airfares so they've asked if I can have him to stay for 2 weeks so they can have a bit of a holiday - they'll come back on Christmas eve. That is fine, DN is lovely and I'm happy to have him.
BUT, I'm back at work after M/L next month and won't have enough holiday to take time off to cover DN' stay. DD's school won't finish term until 3 days into his stay and although she's only in reception, I don't want her to miss the last few days if we're not going away. I would also rather use my holiday as much as possible to spend time with my children and DN, rather than DN on his own. DH's holiday year finishes in December and he has absolutely no leave left.
I've spoken to the CM my children go to and she is happy to have DN as well.
My sister is not happy. She is a SAHM and is really annoyed that I would be sending DN to a childminder. She has said she thinks I should take unpaid leave to look after him.
AIBU to say that if she doesn't want DN to go to the childminder she needs to either find someone else to look after him (not easy btw) or not go away?
