my ds is 23 months and over ths last month has had a problem with his poo, he crosses his legs and will hold on until it builds up so much he is in agony. He was prem and still has hospital visits to check on his progress, Dr gave us a liquid to soften poo but even tho soft wont go, not tried potty training yet. Its awful as he literally screams when passing a poo . Can anyone help please xx
