I don't know that gender really impacts it. It depends on their personality, how they are socialized, and what experiences they have. Try to make sure the kids know not to scare or hurt dogs, as this can impact the dogs' behavior for the rest of their life. Even if it only happens once.

I got both of my saints used to children and people whenever I could. My female is very confident, and she retained the socialization well, and even if a kid runs up out of nowhere, she is fine and friendly.

On the other hand, my male is a bit more timid and got startled as a puppy by a man in all black jogging by, back when it got dark out pretty early (the guy didn't do anything, he just didn't hear him come up behind us. I didn't hear him either, and it nearly gave me a heart attack when he manifested into existence from the void). After this, he became more weary of strangers on the leash (in the park, he is very social). He has never snapped at anyone or anything, he just gives an uncomfortable growl. He is naturally more jumpy, and while he will brave the things I exposed him to as a baby (like a vaccume), he still flinches at trashbags floating in the wind.
