Hi, (new to this) my two and half year old son suffers from terrible constipation, he is a twin and his sister is fine. His diet contains lots of fibre and he drinks well, loves fruit and veg but he is very blocked, he is having trouble potty training as he has what we call 'poo farts' alot, so not much substance but little bits now and again. Has anyone any ideas been to the doctors 4 times they seem unconcerned. Tried Lactulose, sennacot syrup, figs you name it??????
