DS has little variety in his foods. As of now, he only eats fruits, veggies (baby food) and oatmeal. Oh- and tons of cheerios

I tried pastina over the weekend- he didn't like it. Should I try mixing it with something else?

I am confused with food allergies- do we still introduce one food every 4 days? A lot of what we have is mixed..

He has 8 teeth already- so he chews pretty well!
