I found this article very interesting. It talks about how babies cannot properly digest grains until they get their first molars. Until then their body is not producing the enzymes to digest grains (wheat, oats, rice, quinoa, etc.)
We had started giving Leland quinoa prior to me reading this article, we have now stopped that. Unfortunately Leland will not be able to experience the deliciousness of bread, pasta, rice and quinoa until he gets his first molars. He still gets his teething biscuits that I make, only because he doesn't really eat them, he just gums them then throws it on the floor for Heath to lick. (Yes Heath likes teething biscuits, egg yolks, broccoli and kale, and he has already figured out this kid will drop food on the floor for him.)
For now he will have to stick with vegetables, fruits, beans, eggs and meat. We may eventually introduce some cheese, but I am a little cautious about it since he has been so sensitive to me eating dairy.
He really loves his veggies.
