I'm impressed with how affordable this high quality formula is. My first four months of breastfeeding went great, but due to high stress with four big life changes, my supply dropped about 50%. My baby then wasn't where he needed to be on the weight gain curve. We tried so many different avenues before deciding we should try formula. I was so sad that I had to turn to formula because in my opinion the majority of formula products on the market have garbage ingredients in them. After doing lots of research and searching online I found Byheart. It's the only formula I felt comfortable with giving my baby due to ingredients. We are now combination feeding and he has been thriving! The one and only critique I'd have for it is that it's instructions say to SHAKE WELL. That causes froth and bubbles to build up that can't be broken down. I have to "swish" VERY WELL and that's what actually works. I really love this formula and I'm glad my baby does too. Thank you Byheart!
