When my son was born in December 2007 I started giving him Enfamil Lipil, and he started throwing up, and everyone told me I was over feeding him. When I took him to the pediatrican she told me he might have a sensitive stomach and told me about, and gave me a sample of Enfamil Gentelease. I took it home and tried it. It is a lighter color than Enfamil Lipil. When you mix it it also gets a little more foam than the regular Enfamil. Otherwise it is a great formula.  It works really well on babies that have a lot of gas too. It does cost a little more, but not nearly as much as the Neutromigen....
