I know I'm probably being very nosy and U but I can't help but worry and wonder if there is anything I can do!
I've recently made friends with another mum who has 2 DD's, aged 2 and 3, lovely mum, lovely kids and my DD (4) gets on well with them. The other day I went out with them while my DD was at school, we went in their car, when i got in I noticed that both girls had their arms out of their straps, and said 'oops, looks like DD's have taken their arms out' (I know a lot of kids do this, I'm lucky that my DD decided not to pick this battle).
My friend didn't seem worried and said that they won't wear their straps at all, they complain if she tries to strap them in and have tantrums, but she thinks they are fine as 'at least they are sitting in their seats and they are padded', and it doesn't worry her. When we got out of the car it became clear that the straps weren't on at all and just hanging over the sides.
I might be over-cautious as I had a friend who's DS suffered a nasty stomach injury when he had taken his arms out and their car had been rear-ended and the buckle dug hard into his tummy. I didn't mean to judge her, I'm by NO means a supermum and DD is not a saint, and we all have our things that our kids won't do, but they should. I can't help but be a bit alarmed that their mum doesn't think it's worth doing something about.
I'll wind my neck back in now!
