Dear Ma'am, Very Good morning to you.  I'm Dr.Yogesh Kr Sharma.  I think you should consult a Paediatrician and Rule out HIRSPRUNG'S DISEASE. May be this is the cause, but God forbid,  May not be your baby suffering from above mentioned disease. Same thing happened to my baby,  he was passing stool in once a week. So we went to Medanta - The Medicity,  to Rule out this disease,  but after doing ANAL MANOMETRY, the conclusion came up,  that potty habbits of my child at the age of 1 year is normal and not suffering from HIRSPRUNG'S Disease. We were Very happy. I suggest you to stop using Glycerine and seek a good Paediatrician in your area to Rule out the disease,  as we did It. take care and have a hasty recovery for your baby.
