Quite sure I just pissed off MIL. On a scale of 1-10, how U was what I said...?

[BeyondTheLimitsOfAcceptability]

It was an accident and kind of came out wrong, but she pulled catsbumface and left (she was picking up DS2)

She has a small car and I was saying DS1 was off nursery next week so she could have both of them if she wanted. She said she couldnt fit the three seats in the back and I said that Dcousin (he is 3) could sit in the middle without a carseat. She said he needs his booster, and I said "well he should be in a carseat, he'd be just as safe in the middle with just the lapbelt as he is on the booster" (he only has the lap belt with the booster, is too small for the diagonal one) I know I was BU and its none of my business, either his mum has decided he doesnt need a carseat and theres nothing MiL can do, or she has decided it and I've directly complained about her choice.

I feel bad now, even though I think what I said was technically right, I was just trying to explain that she could have all three of them if she wanted. She is the one who's been saying how nice it would be to take all three out for the day. :(

"He already is at risk, he is a three year old on a £5 booster" Well, fuck him then. Might as well strap him on the roof.

YABU. A 3yo needs to be in a proper child seat.

She can't have the 3 of them though really, not safely.
I don't have the cognitive power to score you, sorry.

Probably best to apologise for being prickly.

Are you pissed off that she can't take both your kids out because she has their DCous?

AnD she's a brave woman to consort taking out three under 4!
Impressive!

• Consider.

She was fine when she came back so I chickened out of bringing it up again

mike I did say upthread, the reason I said that was because I'm sure I've seen here before that a booster seat doesnt offer any protection (which someone has agreed with upthread - the point being to raise the child up to the right level for the diagonal belt, which makes it pointless if just used with the lap belt) If I had any say he'd be in a 5 point harness still, regardless of him not being my child. IMveryjudgeypantO, he should not be on a booster seat, and of course if she cant get them all safely in the car, she cant have them all at once.

emily when I was pregnant with ds2 she laughed and said she'd never have the three of them together, and downsized to a smaller car then. She is the one who now does want them all together, it doesnt bother me either way!
