Have been into diapers on and off again for years. My love for diapers started when i was young. I can rember being diapered in a pink luvs by my cousin's mom when i was around three or four.
I can also rember one other time i was diapered by my great grandma when i was around the same age. now keep in mind that i no longer needed diapers anymore but i had cousins that still wore them at night.
I don't know if they needed them or if their parents felt they needed to be in diapers at four and six years old. this was back in the early 1980's.
