For the last week, my 3.5yo DD has been having between 1-4 poo accidents a day at preschool and home. She's been toilet trained for well over a year now. We had a few weeks of wee accidents about 4 months ago but that resolved itself. I can't figure out if this is constipation or something else. Her poo is a mix of fairly hard poo and normal soft but formed poo (sorry, TMI) and she's not complaining of tummy pain or pain when she actually poos (no straining). Can anyone help me understand?!
