K.,
When my son was about the same age as your son, all he would eat was graham crackers and bananas. And he stayed healthy.
We kept offering him other foods which he would refuse. But he did, after some months, start eating these other foods.
My advice (and I'm a grandmother now) is to be patient, be thankful he's eating, and I'm sure he'll surprise you one of these days and start eating more variety. In the meantime, give him a good children's vitamin supplement such a Shaklee's Vita-Lea Ocean Wonders.
Best wishes,
