I don't know if I've done something awful here, I can't stop thinking about it and have had a bit of a family fall out!
DH younger sibling (14) stayed with us whilst his parents were abroad for a week. We have a DS who is 1. We are in a maisonette and DS bedroom is next to the living room and ours is next to the front door.
BIL was sleeping in the living room. Friday last week, DH went to work at 6am and all of us were still asleep (BIL had inset day).
At 9am I woke up in a panic that I hadn't heard DS, then realised my bedroom door was shut (we are also looking after parents dog), he'd come into the room and laid down and obviously knocked our bedroom door shut as was laid against it. I got up and DS was playing in the living room with BIL. I apologised that I hadn't woken up and it was no issues with BIL, they were playing with toy cars and blocks and DS was happy (although sat in the nappy he'd been put to bed in and hadn't had any breakfast).
I immediately changed him, gave him some weetabix then got a few very unhappy messages from MIL basically calling me lazy and that her son wasn't there to "babysit". I messaged back explaining that the dog had shut the door which meant I hadn't heard DS calling out for me when he woke up at 7:30 (I looked back on the camera to see how long he'd been up for). She had FaceTimed BIL and he was with DS and she obviously knew I was still in bed. She replied asking what time I usually respond to DS calling out for me and does he just sit in his cot until I get up? I read this and didn't even reply because I was so offended, I'd never leave my son to cry in his cot. I'm usually up with DH when he leaves for work. I also haven't been well recently with my endometriosis and I'm currently experiencing a flare up which prevents me falling asleep due to the pain. I must of dozed off eventually and gone into a deep sleep to wake up at 9.
I called DH whilst I took the dogs out for a walk with DS and DH was and still is upset with his Mum for the shitty messages she's sent me and laughed it off to me saying at least I'd scored a lay in and that BIL was perfectly capable of playing and supervising DS for an hour.
I haven't spoke to her since, no thank you for having BIL and dog, I took him to school and picked him up, we went out for dinner, we fed him for the week, I walked her dog every day with mine. I've heard nothing. She's obviously pissed off with me and it's making me feel like it is obviously a big deal and I'm a bad mum.
