Ages: 5-8

I guess my experience with diapers started when my younger sister was 
born. She was 15 months younger than I was. My parents were divorced, 
which I think was a contributing reason why mom treated me differently. 
I lived with my mom during my childhood (my father didn't want to have 
anything to do with me or my sister). I was given a lot of latitude in 
acting babyishly. My mom always said that boys mature later than girls, 
and she seemed to go out of her way to prove her point. My mom's 
grandparent's had left her a sizeable trust so she didn't need to work. 
Until I was four I didn't think there was anything wrong with wearing 
diapers as me and my sister always wore them. I remember my mom giving 
my sister a brand new pair of big girl pants. I got really mad and 
asked where my big girl pants were. She told me I needed big boy pants 
and I still had a long way to go to get them. My mom enlisted my 
sister's help in potty training me, she thought it was cute to have my 
sister check my diapers when my mom's friends came over.

"Is Jimmy poopy?, go check your brother." I was day potty trained 
before the first grade. At night I wore diapers until I was 8. To this 
day my sister still treats me like I am a kid. My mom gave my sister 
full reign over me. Can you imagine a six year old asking a seven year 
old if he needed to "go potty". My bed time was 7:30, my sister's was 
8:00. We had a ritual each night, my mom would tell me to go get a 
diaper. One day my mom was on the phone and my sister said to "go get a 
diaper". I told her that I wanted mom to put it on me, she said I 
better get one or she would give me a spanking. Even though my sister 
was younger, she was about the same size or a little bigger, when she 
came near me and pulled my pants down I started to cry.

My mom got off the phone and wanted to know what was wrong. My sister 
told her the story, and my mom said that she was very mature and I was 
very naughty for not doing what she said. Mom gave me a spanking and 
told me that if my sister told me to do something I better do it or get 
another one. My sister took this to mean that it was free reign on me. 
My sister always made sure that she beat my mom for asking me to get my 
diaper.

One day, when I was about 8 we were going to go to the beach. The day 
before I had tattled on my sister to my mom about my sister tracking 
mud into the house. My sister was really mad, after all, she was the 
one who was supposed to be grown up. My sister helped my mom pack for 
the beach, I was free to play my toys. While we were at the beach I was 
playing with some other kids, my sister told me that mom wanted me to 
come for lunch. I told her that I would come as soon as I finished my 
sandcastle. My sister told my mom that I wouldn't come which really 
made my mom made. In front of the kids I was playing with, my mom 
grabbed me, pulled down my pants and spanked me then dragged me back 
for lunch. My mom was still really mad, and my sister took full 
advantage of it. "Mom, I think Jimmy needs to take a nap" and with that 
she produced a pamper. My mom didn't have to think twice, she pulled 
off my pants and I was reduced to a baby. This was in days when Pampers 
were plastic, so they were really crinkly. I tried to go and play with 
the same kids I was playing with, but they just said they didn't want 
to play with a baby in diapers.

This was one of many real life humiliation I suffered when I was a kid.
