My friend always wanted to tkae babies for a walk but I didn't as I thought they were boring. I had the same opinion on dolls too, but my mother insisted on buying them for me because girls didn't play with train sets 
I wasn’t allowed to play with my dads train set. He got it out once. It was given to my cousin. I hope he appreciated it! I made up for it by playing with my childrens Brio train set and later my son’s electric train set, but only under his supervision! I bought my daughter a toy plane and my son a boy doll, when they were toddlers. He played with the plane and she played with the doll! I think as parents you should let your children make up their own minds what they want to play with.
When I was 17, I did work experience in my old primary school. I was left alone with a class of 5 years olds at times. Obviously they trusted me, but think of the insurance implications these days! What if something happened?
