I don't know. I came into all this in adolescence, as a urine fetish. Maybe I defy the traditional labels, or maybe I do fit them and just don't realize it? Due to religious guilt, I didn't give myself the chance to explore any of this until my 30s, so I feel as if I'm still learning more about who I really am.
I definitely enjoy diapers, both cloth and disposable, although I find myself in disposables more often because of their convenience and being able to more easily wear them outside the house.
Although I've explored various ABDL items such as bottles, sippy cups, and pacifiers, I've never felt any desire or ability to regress, and these items tend to become disused not long after I acquire them. I keep them around because they're cute. I do have a large plushie collection, however (almost all are ponies, of course). I have a giant unicorn plushie on my bed to hug when I'm feeling lonely. I also have a large collection of pony and hello kitty cups.
I've been redecorating my room to be more cute and pink, with a mix of pony and hello kitty. Pink curtains, pink bedding, white furniture, rugs, etc.
I secretly cross dress under my clothes with pretty panties and socks all the time now. Sometimes I'll wear a skirt around the house when nobody else is here. I also wear girly long nightshirts when no one is here. I paint my toenails often.
