Which dragons do you think would be good with kids?
Well there's a lot of Dragon's that could be good for this, so I'll just answer with what I think is the best Dragon from each world.
For Artisans, Argus would definitely be the best with kids. Even with the small amount of cutscenes that we get with the Reignited Dragons, you can see Argus taking care of the hatchlings and he clearly knows what he's doing.
For Beast Makers I think Lyle has the best chance? He's a lot less rough looking than the other Dragons in his group. Plus he already seems pretty friendly, so that would make him easier to approach.
Magic Crafters is a bit tough to pin down, but I have a feeling Eldrid would know how to handle them. He gives off the 'cool teacher' vibe, so he'd be a good fit.
For Dream Weavers, it would definitely be Lateef. I think I've said this already but he seems really nice and easy to talk to. And he seems like he has endless patience.
Peace Keepers for me is probably the hardest for me to choose from since I can't see any of the Dragon's from here ever being mad at anyone. Like they look tough but at the same time they'd most definitely smile at any kids who come their way. Buuuuuut... I'll just say Magnus. He'd be the cool fun dad that all the hatchlings like to hang out with.
