Teething 8 month-old

Patient: I have a 8 month-old who has three teeth coming in. The last four days he has had really bad diarrhea but no fever. He still has wet diapers and is eating, but as soon as he finishes a bottle it goes right through him. Almost every one is a blowout. Do I need to take him in to see a doctor or will this go away on its own.

Symptoms: Diarrhea

Doctor:
