They have a 4-month-old baby. Lovely people, have had trouble with setting the pram up and so on so I've been popping in and helping them every now and again.
One of the things I did was fit their car seat, as they couldn't make it fit. It took a while (bad fit) but I managed it. The dad grumbled that it was v hard and complicated.
And several times since I've seen them driving out, with the mum in the back holding the baby.
What to do? Don't want to be a busybody and report them unnecessarily, in all other respects they are concerned and loving parents and the baby is very content.
OTOH how would I feel if there was an accident?
They are not stupid people, BTW, so pretty sure they know the law and surely they must know the risks?
