I have always been young at heart, and a member of the furry fandom for a few years. If that does not make me a baby fur to any extent, I don't know what does.
My fursona is a winged wolf that, while he may vary in age, is always a big (or little as the case may be) pup, and is often willing to lend a hand in caring for others.
real life: I have tried and like diapers, but prefer to keep that private or only among others also interested.
I am usually fairly easy to get along wiith, I try not to force anything on anyone if there are clear signs they are not into something and I prefer to have that same curtasy extended to me.
