My daughter was diagnosed with Protein Allergy or Cow Milk Allergy aka Lactose issue I guess. When she was on my breast milk she had broken into redness, rashes, and stomach swollen. When her doctor recommended that we try Nutramigen that day we saw huge difference. Within 2 weeks the first 3 months of suffering had gone away. She was sleeping better, less gassy, and more full. She is almost 8 months and is in the 75th percentile of her height and 50th percentile of her weight. Perfect size baby! She is crawling, standing, and full of energy. Her motor skills are so on point to her age or more advanced. I had bad vibes about formula way before I was even pregnant, but I will say this is one of kind. Recommended to two of my friends who just had a baby and has been also the best option for them. Thank you Enfamil!!!
