Yes, they were around until the the early 70's. The suuper size were very large, bigger then gerber todler size at the time. And yes they were used by parents for bedwetting older children. I seen kids from 4 up up wearing them. My mother babysat kids for a living when I was grwoing ups and was quick to diaper a kid no matter the age at any hint of wetting or pooping in their clothes. So I seen kds of all ages in them. Most of them were boys but there was a few girls. Including my brother until he was 9, and 3 of my male cousins until the oldest was in his late teens.
