I was feeding him the formula, but e started coughing majorly, so I backed off of it for a few days. Now he eats blended banana twice a day, and oatmeal twice a day, till the crop is filled. This diet isn't bad, and isn't much different from the formula, which is based on soya and wheat.
I will try the formula again in a few days. I believe I had the formula too watery of a consistency. I was averaging the 1/3 formula to 2/3 water. Now I will use tablespoons to measure the amount of water to formula, and I believe I will end up with a thicker consistency, much like the blended fruit, and blended oatmeal.
