My daughter is just turned 3 in March and she will go poop on toilet but when it comes to pee she does it in her undies and pullups...and i have been doing if since then...i was asking some other people and they were saying that if there is a new baby in the house or if you are paying more attention to the others then toddlers act up more than they usually do.... if you get any ideas help me too i am there too. i need to get her potty trained for preschool and she acts like she is not interested at all.....im there with you....please get a hold of me if you find anything out..
