For reference, DH and I had to move in with my parents a couple of weeks before my birth (had a huge flood, ceiling beginning to collapse etc). My parents offered us to stay with them until we managed to get the house ready/or find a more permanent solution. MIL had the same space available, however didn't offer (which this doesn't bother me in the slightest, only mentioning it because it'll be relevant)
forward to my delivery, i stayed at the hospital for 3 nights, barely got any sleep and due to some
complications, was in a lot of pain/sleep deprived/struggling to breastfeed as baby didn't latch and the hospital didn't help much out in that department. when i got home, i just wanted to rest and let my husband take care of the baby so i could get through the night.
MIL invited herself in unannounced, i mentioned i didn't think id be having visitors just yet, as it was the first night and 9pm. she replied with how my parents were so lucky they'd see so much of my daughter, and my in-laws didn't have that privilege so she thought it was only right she saw her on her coming home night too.
i didn't say anything not wanting to make anyone feel unwanted upset or even make it seem like i was prioritising my parents. but after better sleep and reflecting on this, i think i'm a little P'd off at her response of my parents privilege when she didn't offer once for us to stay with her. i think the way she made the comment in the snarky tone might've been part of the reason i'm so worked up over it.
i didn't intend on having visitors, and of course living with my parents at that moment made it so it wasn't just baby, DH and I, so I didn't want MIL to feel left out, but then, AIBU to think she should've asked first at least, given the situation?
