We had to find formula for my baby when my supply started dipping at 9 months. We used a different organic formula brand and baby seemed okay with it. But I ended up switching to ByHeart when the store I was at didn’t have that other formula, but I saw ByHeart and thought I’d try it. It was a bit more expensive than the other one we were buying, but again, wanted to give it a try. And wow! My baby loved it! He guzzled it down! He also had very minimal spit up and and gassiness! Total win in my book and we’ve made the switch, totally worth the extra few dollars!!
