Charlie's "best friends" to date have been mostly boys. He likes to chase his friends around, so a key criteria for Charlie's friendship is whether or not you are faster than him haha.
He also likes girls though. Mostly he likes to feed them his food, which he doesn't eat. If they are good eaters though, he gets inspired and starts eating himself! He can be a picky eater at times, so we're just grateful when he eats.
Basically Charlie seems pretty comfortable with both genders. Maybe time will tell a different story.
Is your LO prefer to play with mostly boys or girls, or do they not seem to have a prefernece?
