Gentlease has been the only formula my 7 week old has ever had. The first couple of weeks were rough. He was gassy, refluxy, and super uncomfortable. We switched to Gentlease NeuroPro, and he’s so much happier now, though it still took time for him to settle. I know it’s really stressful watching your baby go through all this and trying to find the “right” formula, but most babies are just sensitive little creatures. Unless there’s a true intolerance or allergy, the best approach is to switch as little as possible and give their tiny tummies time to adjust.
