I totally agree with Shelly C.,forgr the pull-ups and diapers,they are a comfort tool,and fall back,for the kids.My youngest son held his poop for almost a week because he refused to go to the potty(he was "pee-trained"),it was not a pleasant time.Every time I saw him squat,to the potty we went,sitting and sitting and sitting,'til finally mother nature took control of the situation,the "poo" came out in the potty,of course we made a big deal for the "big boy" and had to for some time,finally had to wean him off the poopy praise.I know this is a lot to ask,but it also helps to know there poopy habits,ie. soon as wake ,up noon ,etc- that helps considerably.But I only had one to deal with,if you accomplish this with all your hair in tact,I salute you and the rest will be a piece of cake,well,until they are TEENAGERS!!!!!!! Good Luck
