The age at when most babies stop wearing diapers is between the ages of 18 months to 3 years old.
However some babies and toddlers may wear diapers still until they are 4 years old.
The age at which babies or toddlers potty train varies from child to child and there's no right age for a child to potty train.
You can try potty training your child by age 18 months but if they won't potty train then just keep them in diapers and try again when they are 2 years old or 3 years old.
Some children are not ready to potty train and stop wearing diapers until 3 years old and even 4 years old.
I have a 5 year old that is just getting potty trained although I tried before.
My 5 year old son is still wearing diapers full time and wears Gentle Steps Size 7 diapers which fit him really good.
I think he'll be potty trained before age 6 which I hope so but he may need to wear the diapers at night.
I tried potty training him before when he was 2 and 3 years old but he was not interested and I was not gonna fight him on it.
I just put him back in diapers and let him decide when to stop wearing diapers.
He has been using the toilet for pee and poop most times but sometimes he wets the diaper or poops the diaper.
He'll eventually get the potty training and decide to give up diapers.
