AIBU for refusing to let my MIL babysit my daughter for the weekend?

[FrenchMomM]

DH and I are invited to a wedding near his hometown in a few weeks.
The original plan was to drop our daughter (1,5) to my MIL's place for 2 days but as the event is coming closer I am strongly reconsidering this choice.
My MIL and I dont get along really well, nothing serious but we really don't have the same centers of interest or views on life in general.
What really bothers me is that my MIL as come to see our daughter only 3 or 4 times, and has never been alone with her (always in big family events, birthday or christmas). She moved to a new (very small) place this year, that I've never been to, nor my daughter obviously.
My MIL is 62, lives alone, and has been too tired to come and see us those past months (it's a 3 hours ride).
AIBU for not wanting to let my daughter there for 48 hours and thinking she should first get to know her, and care for her step by step?
DH said that it made her mother really sad to not have her over the weekend.

Really eager for your thoughts on this!

You moan that she's only been to see you DD 3-4 times in 1.5 years (average or above average for a grandparent who lives 3 hours away IMO), but you also say that you've never been to her new house? Sounds like you're moaning about the amount of effort she puts in, whilst putting 0 in yourself.

Yanbu it's not about your mil feelings, it's about your very small child being in a place and with a person she hardly knows. I would send her to your dp's. You will be worried sick the entire time you are away from her.

I think you are right not to send your DD to someone she doesn't really know.

I think you should start to work on building their relationship by visiting her more going forward.

If the wedding is near DH's hometown why do you need 48 hours worth of babysitting? Go for the wedding and then go and stay at MiL's or pick up DC as soon as you can the next day.

But yes, also go and see MIL.

Is it really 48 hours she will be looking after your dc? If the wedding is near MIL surely you leave child just before wedding and are back by latest the next morning. It should be no more than 24 hours.
