I depends on how one defines a “doll”.
Both of my sons are infatuated with Superman “action figures”....which are dolls of a sort. They gravitate towards them.
There are two girls in the neighborhood, who have baby type dolls. The boys play with the dolls when they play with the girls. The boys treat the baby dolls the same way that they treat Superman “action figures” and don’t really make the connection. The dolls are whatever they want them to be, not what we as adults see them to be.
Well that is right, we had these very cool Buzz Lightyear and Woody “action figure” dolls, and also Power Rangers and transformables, all of which are dolls of sorts. And my boys had a huge load of stuffed animals.
If a boy can transition betweeen an obvious boy figure and an obvious girl figure and treat them both the same, I’d entertain the thought that something is developementally wrong.
Hence the term, "Action Figure".
