Dear gemmaob1234 I am sorry to hear about your daughter. Green vomit is produced by breakdown food
and presence of bile, but it should not be ignored. It may be due to some serious condition. You mentioned
she appears happy and does not look dehydrated. Please do not take the face value thecondition may turn serious. My advise will be to take your child to hospital to have full and thorough investigations which include Biood culture/sensetivity, urine and stool culture/sensitivy Blood urea electolye to asses dehydration
, Type of dehydration. I believe she will be better soon. Kindest regards.
