My son is 2 months old and he has pooped twice today the second time i had to help him but his poop is clay like and greenish grey is this normal?

Normal: The stool color is provided by the bile from the liver that is adds to fecal debris.It starts out a deep green & slowly changes thru greens to yellows to browns as the germs in the intestines metabolize the bile.Green generally means the stool in question moved through faster or was subject to less change by gut germs.

See below: The bowel movements should be soft. The color may vary. His stools sound normal.

See below: Color is ok, the clay is a sign of constipation. At two months, try adding dark karo syrup - 1 teaspoon per 2 oz of formula. This should pull water into his gut and soften the stool. This is assuming that the child is getting formula - if breast fed primarily, see you pediatrician.
