My 2 year old is going through some sizing issues right now. He is getting taller and thinner than he had been...(he was very chubby for a long time). Now his large FB when stuffed with only one insert fall off him...so I tried medium and they fit sort of wierdly on him (I think the rise is just a little too short so they don't lay flat in front...they bunch). PT size doesn't fit him right. If I stuff the large FB more they fit...but I want a trim diaper. Does anyone have any suggestions for a trim diaper that fit toddlers well (he still isn't petite or skinny). I am moving toward doing all AIOs and pockets just for ease of use. Any suggestions are welcome.
