Hi L.,
I have had great results with Good Start Supreme, Natural Cultures with DHA & ARA. It's their new formula with the lime green label. My 7 week old son gets one 4 oz formula bottle at night and breast milk the rest of the time. He has no problem going back and forth. My children also have "digestive issues and acid reflux" so it's very hard to find formula they can tolorate. Good Start is also the only formula that uses 100% Whey, which is a protein needed for babies.
Hope this helps and congratulations in your pregnancy!
