|my sisters dd is huge, over 25lbs and only 12 months old, (and I thought I had big babies) anyway she has very big thighs and belly, and wears the onesize, the diaper is very stretchy, (I totally didn't think they would fit her, since she was 22lbs at 4 months. (my kids are 20lbs at six months, Kids slow down after 6 months. my kids were only 21lbs at 1year old)
Anyway, the diaper fits my niece, fine and comfortable without the liner (with liner its kinda tight) so the diaper does get easily soaked but the kid is comfy, with disposibles, she gets chafed.
PP-how do you find the diaper extender, this may help my sis be able to use the liner, so the diaper wont have to be so thin for her baby?
