My son is 3 months old & has had trouble having BMs the past couple days (excessive straining, screaming in pain, etc...) Today I had to give him a glycerine suppository to help him produce a BM. When he finally did go, it was grey with white specks and had a mucous-like consistency. I could see the remainder of the suppository in his diaper, but this has never happened before when I ve had to resort to using them. Should I be worried?
