Yesterday we had some relatives over, when they were leaving DH walked them out and later he told me they didn't have a car seat in their car for their 4yo. That reminded me that years ago when our kids were only a few months old we had a conversation where the mum said she still didn't have a car seat (her DS would have been almost 1 then) and asked me for recommendations. I was very clear that she should get one asap and told her which one I had and suggested some places she could get one.
Yesterday when DH told me I was shocked that 3 years later she still doesn't have one and I assume her child has never been in a car seat. I'm really uneasy about that, it's so dangerous.
This family is the type though that if you say anything to them they can fly off the handle and turn things into huge family fights. Would you say something or just keep your mouth shut. DH thinks I should say something and I do too but I'm wary of getting involved.
