My DD wets more than most and I find them just as good as an itti bitti. I use boosters in my GM's.
Fit wise right now I find them a tad bigger than the itti bittis but that is cause DD is so small.
I have some listed for sale if you wanna try one.
I always say this but the reason I use them (besides being cute) is they always make my DD smile, so I assume it's nice on her bum
