I'm also a diaper lover and wear diapers full time but I'm not 13 years old anymore but instead an adult who loves to pretend to be a baby and toddler.
I wear diapers full time now and have a good job that I can afford the diapers and haven't used the toilet anymore since 7 years now.
I wish I could've wore diapers full time when I was 13 but I couldn't afford it then and it was hard for me to hide the diapers.
I did however used to wear Pampers diapers under my pants in front of my family sometimes and they never noticed.
I used to also sit in my room in just a diaper and T Shirt and it felt so good to just wear the diaper and sleep in just a diaper.
I also love to wet the diaper and poop the diaper and sleep in just a wet and poop filled diaper.
I am a diaper lover myself and love to act and dress like a toddler and baby sometimes when at home.
I'm an adult now but have loved diapers since I was around 5 years old.
You're certainly not alone in wanting to play as a baby or toddler and want to wear diapers.
There are thousands of kids, teens and adults out there that have a love for wearing diapers as they feel very good.
When I was a toddler I wore the old plastic backed Pampers diapers and now I wear Abu Super Dry Kids diapers which are a replica of the plastic backed pampers diapers that I wore as a baby and toddler.
Wearing those diapers makes me feel like a baby and toddler again.
I also go to the beach in the summer and wear my diapers without any pants and play in the sand and it's very fun.
As for getting your parents to treat you like a baby I personally just would not tell your parents about your love for diapers because it could turn badly for you.
It's best to just keep your parents out of your diaper fetish and the less they know the better.
It's nice in fantasy to want to have your parents force you in diapers and treat you as a baby but most parents will not force you to wear diapers or treat you as a baby.
Just buy diapers yourself or maybe fake wetting the bed and ask your parents to buy diapers for you for bed wetting.
They might do it and then again they might not.
I would just buy the diapers yourself if you can and when you move out you can be a baby or toddler and wear diapers as often as you want.
I now wear diapers all the time for both pee and poop and have not used the toilet in 7 years now and plan to use diapers as long as I live.
