I would think that it would be fine to mix the powders and add the water, as long as you’re using the right ratios for each. I’ve never made goodstart so I’m not sure if it’s the same as the alimentum, one scoop per 2 ozs but I’m sure if you’re using the right amount of water for powder that it would be fine. Did you already give it to him? I’m so interested in seeing how he does!
Also, I don’t know about mixing the formulas but I do know that when we added milk our GI doctor had said we could do it however we wanted – whether we added an ounce or two to his bottle mixed with formula, or added some to foods like made him pancakes or something, or just gave him cheese or yogurt – as long as we introduced it to him in small amounts that was how to do it. So I’d think you could either add it to his formula like you mentioned, or maybe give him a cup or bottle with a few ounces in it – either way it would be the same, I think. I would just be careful that you don’t give him too much too fast – that’s definitely what went wrong with our trial.
Good luck!!!
