So ive got a little situation with my four year old daughter. For the past week or so she has been holding in her poop till she has a small accident. She has been perfectly potty trained for 1 1/2 years. Ive tried everything..... bribes, punishment, you name it. I started her on mira lax about 4 days ago. Today is day 3 with no poop. I'm starting to get worried. I'm going to call the doctor tomorrow. Anyone experience this with their kids? Any suggestions? I asked her why she is holding it and she said shes afraid it will hurt.
