Can I give 2 diffrent formulas to my baby?

He's on Enfamil infant. But they have a new formula called Enfamil Enspire .it's got 2 things normal formulas don't but breastmilk does And it's supposed to be really close to breast milk. But it's way way more expensive .. so I wanted to maybe give him 1 or 2 bottles of the good stuff a day along side of the regular .
