per my Dr if it just flows out of mouth it's spit up and if it's vomit it shoots out of mouth with force. my baby vomits so often that he is on meds for it.
My daughter was doing a lot of spit up I mean crazy projectile spit up. My doctor said if they vomit they'll cry . Also as long as they are soiling 6 diapers a day they are ok :)
my daughter has been doing some exorcist vomiting since we got home from the hospital. thank god we have an apt on Monday for it
