I love horses and have some of my own and if DC was a girl would be straight out to get her a pony. AIBU to not want to get a pony for a boy and thinking its a "girls" thing? Of course I know loads of boys (and men) ride - I am not saying it is a "girls" sport, but having a pony, going to pony club etc all feels more like something I would do automatically and from day 1 with a girl, but not with a boy. If he expresses an interest then fine but its not a given like it would be with a girl (even though I know she might have turned out to detest riding and a boy might turn out to be the finest rider the world has ever seen)
