We are surrounded by poop

Our whole house has a pooping problem. Everyone likes to hold it forever cause they are having too much fun, or just don't like to poop, or are scared to poop, or their poop is too hard, or they have diarrhea, or are just not comfortable pooping on the potty. So I am not exaggerating when I say between brad and I we have cleaned more poopy unds/diapers, accidents, skid marks, and wiped more poopy bums than all the parents we know combined. For example on a bad day each child can produce up to 5-6 pairs of unds with a little bit of poo in them and have to wipe their bums at least that many times. Ben has full on pooped his pants more times then I can count on my hands and toes. He waits to long then just can't make it. I find stashes of poopy unds that they hide from us because they know we'll be mad. About once a week I go on a poopy undy teasure hunt. Cleaning up our children's poo is a full time job and that's not even including the baby and her blow outs. My life is a losing battle against poo stains and don't get me started on boy pee ALL over the toilet. How do mothers of multiple boys survive....
