When is too young to be a little?

I'm thirteen, and I'm a little. Nonsexual, of course. I don't have a daddy, I don't have a caregiver. I don't have any interest in anything sexual. I only use little space as a way to escape for a while, since I'm not having the best childhood.

My family is low on money, my mom and dad separated, my older brothers won't talk to me, and my younger brothers hate me. I used to be bullied in school, and I'm very insecure about my weight, since I used to stress eat when I was in third and fourth grade. I've stopped now, and but I can't lose this weight, no matter how much I excersice, or diet, or fast, or take diet pills.

But that's not the point.

I just think it's nice to slip on a onesie, and make myself feel really cute, as me and my dog sit on bed together, and a babble meaningless things to her. I have secretly bought pacifiers, and baby bottles, and all that kind of stuff that I use when I'm home alone. I'm been in little space many times.

But yeah, do you think thirteen is two young? What do you consider the minimum age to be a little?

I know being a little is my personality, and I can't really change that, but I just want to what you guys think of my age, before I tell my friends. Which I know accept the community, but I'm not so sure about the age. Majority rules here.
