Great blog post.
The Youth pull ups or youth diapers are sized larger for kids over the toddler age.
While the pull ups made for toddlers with T are for children up to age 4.
Although some older kids can sometimes still fit in the toddler sized pull ups.
Just like some older kids can fit in a size 6 or size 7 baby diaper.
When I was 5 my babysitter put me in a large disposable baby diapers.
It was either a Luvs diaper or a Pampers diaper which I can't quite remember but it was pretty thick and was all plastic backed.
I easily fit into that diaper she put on me so some kids can fit into a baby sized diaper.
Just like Tommy Diaper Boy who was wearing pampers diapers they fit him pretty good at 8 years old which is what I believe his age was in those pictures.
