So my husband and I have a 4 week old baby. She's amazing, so easy and lovely. Other than the lack of sleep, we're doing really well. She's our first baby and I think we're picking it up!
My MIL loves DD to bits, always wants to see her which is lovely. This is the AIBU bit - it was our first wedding anniversary yesterday, and we were more than happy to have a relaxed day at home with DD and our dog, plenty of snacks and then a takeout for dinner. MIL has spent ALL of last week texting both of us and calling us asking if we want DD looking after so we can go out. I understand it's a lovely gesture and on first offer we politely declined and said we are happy to relax at home (more than happy). As she continued to offer we politely reminded her that DD is exclusively breastfed, feeding on demand and going through a growth spurt therefore we wouldn't feel comfortable leaving her whilst we were out as I wouldn't know how much milk she would need, she might have 1 small feed or she might have 3 huge feeds. MIL couldn't seem to understand and kept insisting on us 'having a break'. We don't wish for one - we'd much rather keep the offer for when we do wish for a break. I'm getting so irritated with her not listening to us! She's never handled a newborn - she adopted both of her sons, which also makes me a little apprehensive to leave DD with her whilst we go out until we've spent a decent amount of time all together for her to get to grips with feeds/nappy changes etc. AIBU to be annoyed by her persistence?! For reference, we stayed in and had an Indian whilst DD napped 
One more - Christmas cards. We're making our own and sending them out, but because it's the 16th and they've not been sent yet, she's written some up for us and sent them out on our behalf so now we can't send our own. Nearly flipped my lid when she text me to tell me.
Sorry for the essay!!
