Or rather would I be unreasonable as I haven't done so yet.
There is a little boy in my daughter's nursery class who is picked up by his dad and his baby sister (and an older woman who looks like a grandmother possibly) every day. Every day they drive past me with the baby sat in the lap of her grandmother and the little boy stood in the back between the two front seats.
Every day. There is one car seat in the car but I've never seen it used. The road they drive along is an accident blackspot (4 nasty crashes in the 18 months we've lived here).
The thought occurred to me the other day that if something were to happen to this little lad and his sister I'd actually feel quite responsible as I'd not done anything to try to prevent it.
I should add that the dad is very quiet and never speaks to any of the other parents so I can't think of a way I could try and subtly talk to him about this myself.
Should I speak to the school? A community police officer? It's not like I want them prosecuted but I wonder whether a quiet word from someone in authority might do the trick?
