My twins son having severe constipation. After completing their first year they had this problem.they are two years now also they are having this problem. We have consulted pediatric surgeon and he said that it is habitual constipation. Usually we give some papaya, greens. I have given dupalac,softools,cremaffin,milk of magenisa. At last we tried homoeopathy also. But it wont works. They are crying to go for stools. If i give medicine they will go otherwise they wont.plzzz help me to recover.
