My baby is 3 months old and passing motion of green color sometimes.

A. Hai good evening !! If baby is on formula feed(top feed) then green potty is common.. If baby is on breast feed then check mother diet if mother having any green leafy vegetables,lady's finger,or any iron supplement syrup or tablet also cause greenish to brown potty. So no need to worry of green,brown potty sometimes ,only concern when baby having loose watery motion,foul ,frothy ,frequent greyish potty or any blood discharge in poop.
