Our newborn was struggling with reflux and my milk wasn't coming in as strong as I had hoped. We tried different big-name formulas but even the sensitive kind wasn't really working for her. We made the change to ByHeart on a whim and never looked back. Within 12 hours she was back to daily/regular poops, her reflux was subsiding, and the switch between breastmilk and formula was so much easier for her. My husband drove an hour one-way (including a ferry ride) to get the only can within a 2-hour distance for our first try and we would do it again in a heartbeat. The subscription program makes it so much easier to keep it in stock and we never have to worry about running out. Thank you, ByHeart!
