My DD has been having some issues with the pooping part of potty training... She seems to be holding it in ( i have even caught her doing this and she claims that she doesnt want to poop. when I ask her why she just says I dont know.) and she ends up with small amounts of poop in her underwear. this happens about 10 times a day! Some days she doesnt do a full poop at all she just does this all day. It is so frustrating I am about to lose it! This is a regression...she was fully potty trained for a month and this wasnt happening before the regression. Im so lost! any help?
