M.H.
We had the same issue with my son when he was about 12 months old. The pediatrician told me to drop all baby food. Once you drop the baby food (and table food is all you are serving), your child quickly begins to eat more. He also suggested to just continue to put the veggies, meats, etc. on his plate. Let him experiment, and know that he won't starve in the mean time. (Remember it takes quite a few times of trying something before your taste buds usually say ok.)
P.S. It worked for us...now our son (4) eats anything and everything! :)
