My daughter is only 2 years and 6 months old and is scared to defecate. When he did not get the speed of defecation, he pulled it back inwards and did not want to defecate at once. Then she has to defecate by doos and she is also very scared. Lactulose solution usp prescribed by the doctor is no longer working. So the doctor says he has a nerve problem to do an examination for anorectal manometry. The solution to this problem is very good.
