It sounds like you're giving your child a variety of foods which is great! I started my daughter on table food at 6 months because she wanted what her brother was eating. She just turned 1 and now eats pretty much anything. My peditrician gave me the ok to give her almost everything. I don't see why you can't continue to give your son table food and introduce more. I gave my daughter egg at about 9 months old. I gave her the whole thing. I know a lot of people say the yolk, but I never had a problem with either of my kids. I was also given the ok by my ped to give berries and also peanutbutter. I was told that those things are ok as long as you don't have a history of allergies in your family. My daughter also loved cheese and yogurt at this age.
I would first call your pediatrician and see if there is a reason why you can't continue to introduce foods. If you have specific questions about certain things you can ask them at that time.
