I had my first baby last September and both my mother and my MIL are absolutely over the moon and very involved grandmothers. My sister also had a baby three weeks after me and we've become very close through our shared experiences and have supported each other a lot.
I briefly discussed with my sister the possibility of going away together in the summer - hiring a cottage with our husbands and babies so that we could share activities or babysit for each other while we do our own thing. For various reasons, it's not going to happen, which is fine. But I made the mistake of mentioning it to my mother who immediately started hassling me to go away for a week with them. Now from my point of view, this is a very different proposition - not least for DH - they're a different generation, they would want to do different things and my mum would want to spend lots of playing time with DD but not much hands on care. There wouldn't be the mutual support we would get with going away with my sister.
I tried to find a way of saying no that wouldn't upset her, but she wouldn't let it go. She kept on saying "But you wanted to go away with your sister". I felt like I was being goaded into losing my temper with her so that she could be the victim and the injured party and I would then be forced to make reparations - i.e. back down and go on holiday with them. She really wouldn't let it go and I felt very resentful about it.
I thought the whole thing had gone away - they went on a big trip round NZ and it's only been mentioned briefly since they got back, in a 'did you think any more about coming away with us in the summer' kind of way. But yesterday, she called to say that they've booked a cottage in Norfolk for the first week in July. Well blow me if DH and I haven't also booked a week in Norfolk in the first week of July!!! Which she knew full well.
AIBU to think that she's just trying to find another way to get her own way? But what do I do? I'm tempted to thwart her every attempt to meet up while we're both there, but that would be really childish and, actually, a shame for everyone - not least my DD and my dad (although my DH wouldn't mind!!). But I really hate the idea that she thinks she's entitled to invade our private holiday and trample all over my wishes.
How should I handle this??
