Can boys have Dollies?

I'm not sure where this is going to post as I'm new to this and it is my first post. Christmas is coming up and my son is 18 months at the moment. I've been looking at loads of different things, kitchens, scooters, disney toys etc but I have seen a blue soft baby 'brother' I think he would love. When I suggest it to my partner he says no he is a boy. I see nothing wrong with it. Its so sad that dolls/babies and prams have to be for girls when little biys want to do it too. Should I just get him a little baby anyway regardless of people saying its for girls?
