My almost 3 month old has had huge success on nutramigen. She was extremely colicky and gassy and within 4 days I saw a huge difference!
My son is on it, complete night and day difference than when he was drinking regular milk. He still fusses here and there but NOTHING like when he was drinking regular formula
A lot of babies do take it without any issues so try not to stress too much. We were advised to mix it with normal milk to start with and then slowly wean the normal milk out over a few days. My girl wouldn’t touch it and went on complete milk strike but I know a few baby’s who have taken to it without any issues
