Having the usual fun and games trying to cover the Easter holidays. Eventually found somewhere that will take both DC (3 and 7) but only from 10 - 2. DH works from home, split shifts so that he usually can do drop-off/pick-up, but the shorter day means he's stuck for a couple of hours a day. So we have a childcare student who comes in to cover a few hours.
Tomorrow there is no space in the holiday club and I asked DM if she could take them from 10 til 3 or so. She said that was fine. (Background: we've just moved across the road from her, she's constantly at DH to phone her in the afternoon to see if she is there and then send the kids over, she gets grumpy with us if we don't see her over the weekend).
I phoned this evening to confirm times - and now she suddenly can't do it. She says she told me, but she definitely didn't. It's not the first time this has happened and it's getting frustrating. I can't take time off at short notice (I'm taking time off next week to cover some days), DH has no leave left and can't get much work done with a 3 and a 7 yo in the house.
It's like she doesn't understand that we can't be totally spontaneous about childcare. She has even asked why we can't just "play it by ear" over the summer holiday (by which time DH will be back in a 9-5 out of the house office job). We've never demanded that she look after them, and if she had said at the start that it didn't work for her, I would have organised something else - but at 8pm the night before, I haven't many options!
AIBU to be utterly frustrated by this and wish she'd just say no at the start if something doesn't suit?
