question: Hello, my 9 year old son suffers with runny poo! He goes twice sometimes three times a day. It is brown in colour. He is healthy, and we try have our 5 fruit and veg a day. He has a good appetite although he is very slim. I took him to our own gp last year , who said to increase ruffage in his diet. We are still having problems. If he does have a normal poo - he takes a really long time! What should i do?
