Help! My almost three year old daughter has been saying she needs to poop every night after we do her bedtime routine and put her in the bed. She never poops, but will sit there forever and I know she doesn't have to really go, but I can't just stop her from using the potty when she said she "needs" to! I try to make it as boring as possible--no books or songs--but nothing is working. She needs to sleep and I need to cook and workout and clean the house! Aghhh--any advice?
