DH and I are about to have an almighty row and I've had to come upstairs to try and calm down about this so I might go on a bit!
DS1 and DS2 have been out all day with MIL, SIL and DN. SIL drives MIL's car, a Nissan Qashqai. When they were collected by MIL this morning they were both in car seats, DS1 who is 6 in a backless booster seat and DS2 who is 3 in a Group 1 carseat belonging to DN. Tonight when they were dropped off I popped my head into the car as they were driving off to speak to DN and saw that she was in her carseat and only that and the booster seat were in the back.
I came in and asked DS1 whether he had sat in a carseat and he said he had but that after they had picked SIL and DN up he had sat in the middle of the backseat and DS2 had sat in his carseat. He also said that on the way home from MIL's he hadn't worn a seatbelt but had sat "very still."
I am livid, not least because MIL has a carseat for DS2 that we bought for her to use and I have mentioned to her before that it is unacceptable for them not to be in appropriate carseats. SIL has two carseats for DN, the one DS2 was in to start with and another in her car. I said to DH that I would have to mention this to her and tell her that the boys cannot go out with her if she won't use the carseats. He has told me that this is unnecessary and that he is sure they would have used the seats. When I told him what I saw and what DS1 told me he backtracked and said it didn't matter anyway as DS1 is tall enough not to need a carseat. When I told him that was incorrect (DS1 is tall for his age but not as tall as a 12 year old!) and that neither boy was safe he told me that I was just being critical for the sake of it and it's just another opportunity for me to have a moan about the in-laws.
I can't decide who I'm more annoyed with - MIL and SIL for being so reckless with my boys' safety or for DH for thinking it's ok. AIBU?
