I have fursuited dozens of events and have interacted with hundreds of kids. I can usually tell right away who will want a hug and who will cry. The one exception are kids under 1. Sometimes they have a "WTF?!?" look on their faces when I approach, but once I give them a gentle pet with my paw, many start to see me as a giant plushie and will warm up to me. Sometimes I become a plushie and the kid will start to cry when mom tries to take them away from me. I almost want to do some sort of study to see what forms a child's reaction to a mascot.
It also got me thinking about having kids of my own. People have told me that they could easily picture me cuddling a child in fursuit. It's a very nice picture. Would the child treat a fursuit as just another part of the family? Would it mess with its mind? Would the kid grow up thinking that dad could transform into a bear? A nice furry thought *grins* Is it normal for all kids to develop "monsters" at a certain age, or is it possible to have a child like Boo from "Monsters Inc." who doesn't fear such things? And having a father who likes vore will be no help. "Daddy! Daddy! The monster wants to eat me!" "Cool!"
