Can someone please help me because I am at my wits end. My daughter (3.5) who has been potty trained for a year, has regressed totally with pooing and poos in her pants. She got constipated some months ago and since then has regressed. She is now going again regularly with the help of lactulose, but just goes in her pants. When she does sit on the potty she just sits there and nothing happens. I have tried rewards, stickers, princess knickers, threats, everything but nothing works. She doesn't even say when she's been and even if I watch her like a hawk she still manages to poo in her knickers.
I am at a loss with how to help her.
