NC SIL wants to see my kids, but not me....

[ChampagneBabyCakes]

My SIL doesn't speak to me. When I had my eldest, we were on good terms and she got to know him pretty well, and My DS1 made a lovely relationship with her son and loves his cousin. By the time I'd had DS2 (5 years later) she wasn't speaking to me and had pretty much stopped contact with my DS1.

We live far away, so I just covered this up with my DS1 by saying they couldn't meet and stuff.

I'm currently in the area for a few weeks, and MIL told me last night she wants to take DS2 over to SIL as 'she would so love to see him' - he's 20 months old. She met him once at his baptism (when she wouldn't even say hello to me) and has not made any contact since.

DS2 barely knows MIL and won't know anyone else at SIL house, except DS1....

I think it's weird to send my son to a house full of strangers on his own. I really don't want to do it. I can't go with him as I am not invited. AIBU?

YANBU.
You have no idea what she will say to your kids when you are not there.

Event thinking this is acceptable tells you something about how her mind works.

No OP YANBU

As someone who was once the child in a vaguely similar situation it is very difficult to understand why someone treats your parents so badly. My parents managed it well but even so I wish they hadn't bothered.

In the long run you can't have a decent relationship with someone who does not treat your parents with respect. For the simple reason that once you work it out you lose all respect for them.
