When I first became a practicing DL, I was able to wear pampers & luvs size 5 and 6 with no issues, I wore those for 5 years before I had my teenage growth spurt and could not fit in them (talk about devastating, literally in one month I went from being able to tape a size 6 diaper and having the tapes land on the taping panel perfectly to not even being able to having the tapes hit the wings and stay on them (this is before the stretchy sides and the diapers were plastic / a hybrid plastic front taping panel with plastic wings and a cloth like diaper core)
Anyway to get to the point, I wear kiddo's diapers and these are the best replica of baby diapers as far as fit and feel, so if your a DL that loved diapers from the mid and late 90's, try the kiddos out, there much better then the abu sdk's, sdk's plastic feels off and the front is kind of floppy.
Now I wish I was my tiny teen size today with the current pampers baby dry and swaddlers, they look so comfortable, and the flex tapes and wings must be amazing while running around. I really wish there was an adult single tape diaper that had the same taping system as the pampers of today, just up sized.
