My first used enfamil because Similac didn't agree with her tummy. This one I'll have to see which brand will agree with his tummy if I need to use it
Used similac powder and breastfed. My BFF did not bf at all & used enfamil and loved it. She bought premix and said it was the best for her with her 3rd child. All formulas in U.S. are held to strict standards so I wouldn't be too worried about the brand--just use whatever agrees with baby.
Im both breast and bottle feeding too. In the hospital they gave her similac for supplementation (green one). And gave us a bunch of it when we left. She seems to like it and doesnt have any issues switching back and forth between it and breast milk. Plus if the hospital uses it it cant be too bad
My entire family has always used enfamil with iron even since I was a kid.
