I have a baby boy three months old and two weeks ago his consistent mustard seed stools changed to green. Everything I've read goes from one end to the other - don't worry; virus; too much iron; something I ate; peditrician says change my diet -- which is it? I have not eaten anything new that I haven't already been eating; baby is 14# (7# 11 ounces at birth) so weight gain not an issue; and he is happy and content with no temperature.
Advice? Thank you in advance!
