My son is 17 months old and has suffered from constipation since he was born. He was on a specialized formula as an infant until 1 year of age and he has been on Miralax for almost a year now. Even on the Miralax, he continues to pass stool that is as big if not bigger around than a golf ball. He screams and is in so much pain when he does this...it just tears my heart out that there is nothing I can do. I have brought this up with his doctor numerous times but he doesn't say too much about it. My concerns are that the huge stool could be causing damage to his rectum and that he is dependant on medications such as Miralax. I am cautious with his diet....soy milk, alot of green vegetables, fruit, etc. I even give him prune juice mixed with water every few days. Should I take him to another doctor or a gastroenterologist to get a second opinion? Is this normal for a small child? What steps should I take next? Please help.....
