I read your letter with great interest. My daughter is doing the same as your boy. She holds on to her's as well. When she does go she screams and carrys on for ages. I would be really interested in hearing how you get on. I have not taken my daughter to the doctor yet as I was sure she was just being lazy. Now that I have read your letter I am sure that there is something else to it and not just being lazy. Please let me know how you get on. Thanks Heather
