Your son is not getting enough in the way of fluids per day.He needs about 1100ml of fluid a day. It may help to stop him drinking milk if most of his fluid consists of milk and no hard cheese.He can have a little milk on his cereal. See that he drinks plenty of water and that his diet is rich in fruit and fibre eg Weetbix.He is on quite a high dose of Duphalac. This should be reduced to 5ml twice a day. It may help to ask a dietician to advise you as your son has had a significant problem with constipation.
