Looking for advice on next steps. 2 year old has suffered from bad constipation for a while. Takes lactulose in the morning and at night - prescribed 5ml have upped to 10. She eats loads of vegetables, drinks water and spends most of the day outside. But still constipated although now she has started straining and refusing to go. She constantly cries that it hurts and now doesn't even like sitting down. I've taken her to the doctors endlessly who just say its a common problem and also to a pediatrician - but I can't let her suffer like this - it's been going on for weeks. Anybody know any experts who deal with this sort of thing?
