My DD1 (age 2.7) has this at the moment, its been going on for over a week now. We have been prescribed a medicine called Docusol, but it really hasn't helped much. We've had to put her back in nappies, because she is getting hysterical whenever she needs to poo, and we thought this might comfort her a little bit. Its like she's giving birth every time she poos, poor little mite [sad. Am going to ring the GP again tomorrow and see if we can have something else. Doesn't help that she's hardly drinking anything at the mo.
