In the 9 months since my son was born he has had a gi bug, 3 viral infections, 3 ear infections and we are now battling thrush. is he seriously ill?

Needs to see...: a hematologist or infectious disease doctor. That's too many infections in 9 months. He could have an immune deficiency problem. I would get it checked out further if it was my child. Hope he gets well soon.

Children's health: Not likely. Young children need to develop immunity. Did you breast feed? This usually helps with immunity early on. But usually there will be a decrease as you child gets older.

Doubt it: The average kid will lose his mothers protective antibodies at 3 months.They then have an average of 5 respiratory illnesses and 2-3 diarrheal illnesses/yr until age 5.Kids with significant immune problems have chronic thrush from birth and are hospitalized with a bone infection or blood infection by 4 months of age. Ear infections accompany uri's. Discuss with your doc, I see this in normal kids
