Ready made formula?

Alyssa
Just wondering about ready made formula... I bough the enfamil gentle ease ready to eat formula in the bottle and it's super thick! It's like a milkshake compared to my breastmilk and the enfamil enspire formula that I was previously using. I was just wondering if anyone knew if this is how all ready made formulas are, or if it's just the gentle ease type by enfamil. Also if anyone knows if the regular ready made infant formula by enfamil is any thinner? My baby is not picky at all, but he sure does hate this thick milk! It's horrible. I thought the ready made was going to be super easy but it's just caused a bunch of headaches so far!
