I'm not sure this is the right place to post this, but here goes.
CM came to collect DS in the car today (v unusual, she usually walks) and I saw her car seat for the first time. It's a sort of booster seat with sides thing, but it doesn't have its own straps - the car seat belt is the thing that's holding him in.
I was quite shocked, and am kicking myself for not having looked at her seat earlier (he's been there a month). Is this actually legal? I thought that seats had to have integral belts.
And if legal, is it safe?
