While pregnant I did plenty of research on which formula I would want my baby to use. I can’t produce milk so seeing that by heart is the closest you can get to breast milk really swayed my decision to choose this formula. I want only the best for my baby. She made 4 months April 16th and has had no issues with by heart and has been taking it since she arrived home from the hospital . It gives her all the nutrients she needs and her doctors tell us for every visit how healthy she is and they are glad we made the decision to put her on by heart. I highly recommend.
