I can't believe what a difference this formula had on my son. I breastfeed my first two children exclusively for a year, so this was our first time using formula (had to due to medications ). The hospital started him on enfamil newborn which he did fine on till about 4 weeks. He became gassy, crying, bawling up his fists and legs, sleeping intermittently and just plain miserable. We tried car rides, walks, swings, swaddling, walking up and down the stairs (which would settle him the best for minutes) till we switched to gentlease. We didn't see much improvement and decided to try the mylicon drops and gripe water (waste of money and I knew it...desperate parents will do anything) Being a nurse, I researched and talked to many colleagues and Dr's and they all swore by nutramigen. I called my pediatrician and he told me to make the switch! Less then 18 hours later, he's completely content. Burps great, no writhing in pain from gas, sleeps through the night at 6 weeks old. Best thing we could have done!!! I highly recommend it. I have read countless reviews and it hasn't stained any clothes and I didn't notice a stronger smell than any other formula either.
