my 15 month old is 21 lbs and 31 inches long. 90% of my stash is BG 4.0 we have only been cd for 2 months and i loooove it. my question is where should the top of the diaper hit? its stupid i know but im wondering if im doing it right..... we are on the middle rise and it hits about 1 1/2 to 2 inches below her belly button. ive also noticed that the front pouches out away from her body (but if i tighten the snaps she gets dark red indentations) and since she runs around like a mad woman the insert doesnt stay flat... it bunches at the crotch from time to time. we dont get any leaks but im open to hearing suggestions if im just a plain idiot who thinks i know what im doing when i dont!
