Have you checked with your pediatrician as to when they sugest to start meats? My pediatrician says to start introducing meats at 8 months. (White meats (chicken, turkety, etc.) first then dark meats (beef, lamb, etc.))
In terms of new veggie ideas....how about asparagus, tomatoes, pumpkin, eggplant, parsnip, rutabaga or spinach?
For fruit, I've recently tried cherries and will be trying cantaloupe, nectarines, and apricots
