This is my first AIBU but I think I've braced myself... I have a new dd, she's 17 weeks. My MIL is madly in love with her, and this has made a previously difficult relationship between the two of us much better . Much like my dp , dd is almost venerated, and can do no wrong.So far, so good.
We've recently agreed that MIL will look after dd one afternoon a week so that I can start back at work- MIL v happy about this, me with slight reservations. So I left dd there yesterday with dsd 11, and MIL. I'd asked dsd to check baby wasn't being left in her v lightweight stroller for too long as it doesn't support her neck etc but mainly as I dont want her left in there for too long.
Dsd tells me this morning that she'd told MIL " dizzy doesn't want babydizzy in the pushchair too long as she gets irritable". MIL then retorted "dizzy can do what she likes while she's looking after the baby" and proceeded to leave dd in her pushchair .
AIBU to think that she a)is rude and wants a row and b) that she clearly has no intention of following my instructions? I'm aware that this is a minor issue but I feel quite sure that she's signalling her intent to do what she likes when dd is with her- AIBU to be fuming??
