My 7 month old son is projectile vomiting uncontrollaby and he has a slight temp. It's been going in most if the day. He if in good spirits but has?

Careful. Watch for dehydration--urine output? Moist mouth? Good eye contact? Skin color pink? Finger print goes away in less than 4 sec? If vomit is pine green or has blood he needs immediate medical attention. Otherwise you can do slow frequent fluids for him. Pedialyte or g2 gatorade would be best. Call your doctor if the vomiting persists.
