ok, i don't ever post over here, and we don't even ec, but i saw this thread and just had to post to say
we have the same problem in our house. yesterday, my newborn had a blowout, my 2.5 y/o had a really gross poopy diaper, and my 4 y/o was yelling, "Come spray my butt!" from the bathroom.
my 4 y/o also has this really weird habit of having to poop every.single.time that we go out to eat, in the middle of the meal!
