Hello, my little one is 4.5 months and is on Zantac for reflux. I pump but am trying to get her onto formula because I need to get back on my MS meds... She does not have a milk allergy. But I’ve tried various Gerber,enfamil, and similac formulas including alimentum (hypoallergenic). She is miserable on day 3 on all of them... screaming, miserable, and not sleeping. So a few have recommended Holle Stage 1 goat milk based organic infant formula from Europe. Apparently they have higher standards for formula there... but here some pediatricians are leery. Has anyone used this? Or any goat milk based formula?
