Hi there,
I had to do the conversion first, so 1 ounce = 2 tablespoons right? That isn't too much for one feeding, once a new food has been introduced with no reaction, but I always played it safe and when I introduced a new food, I offered one teaspoon for the first couple of days to see if there was any reaction. Then I upped it to a tablespoon and then two. I think at 6 months, my LO was getting 1-2 tablespoons two to three times and day, at 7 months were were at 3-4 tablespoons, and now at 8 months we do 4-6 tablespoons three meals a day. There's no perfect way to give solids, just watch what your baby can handle and when he seems disinterested, looks away from the food, pushes the spoon away, then you're done.
