Organic formulas

Talia
Has anyone tried any organic formulas. I started looking into organic formula after breastfeeding became too painful and enfamil formula seemed to make my baby very gassy. I did try a organic brand called plum organic and it made my son EXTREMLY constipated and his poop was very hard and put baby in a lot of pain to pass stools so that's out... I would like the benefits of organic formula that's easier to digest and better than regular formula. Basically would like the closest thing to breast milk in a store bought can.. If avail... Any suggestions??
