DS didn't have a car seat till he was 2 in 1980, and that was because we went around a corner and the door opened and DS almost fell out, luckily my Mom sat in the front passenger seat saw and grabbed him by the leg!
DF went out and bought one, a HUGE fake leather thing that had to be permanently fitted.
You had to cover it up on hot days or it would get scorching and burn DS's legs when put in!
I wouldn't let DS go off all day tho, I Always needed to know where he was, remember leaving him with 18 year old brother when he was 4, when at Uni and coming home and brother had gone out, no idea where Ds was, got hold of brother, who said Ds was at a friends, BUT DIDNT KNOW WHICH FRIEND!!!!!
Did eventually find him the other end of the estate.
God did I make DB suffer for that!
I also remember being yelled at by evilEx MIL for letting DS go off and spend weeks at a time with same DB (putting him on a coach in Dorset and DB meeting him at Earls court)
Th reason EMIL yelled?
DB is gay and I was sending him to DB and his partner!
DS was about 9 by then.
I dread to think what she thought would happen to him!
(They only had him cos they loved to go to Alton Towers and reckoned they couldn't go without a child )
