I would just make sure you are getting all the nutrients you need first if you are still nursing. Then just give him small amounts of what you are eating. My kids are 8 & 10 now but up until they were 18 months and they didn't eat alot of solid foods. They hated most baby foods and we just feed them little bits of what we ate.
One of my nieces was allergic to everything when she was that age and she ate a diet almost entirely of meat. Not only did she thrive but she outgrew all of her allergies including peanuts.
