I'm choosing to bottle feed my baby

I'm due in 8 days with my first baby and I have decided that I am going to bottle feed. I am using phillips avent bottles. The doctors have already found some slight heart abnormalities with my baby and in order to let my family bond with my baby I'm going to bottle feed so everyone can have the chance to hold and spend time with baby without me hogging him or her.

I signed up for samples at the beginning of my pregnancy and I have received formula from a couple of places. Now I'm just not sure which I should put in my hospital bag.

~Enfamil

~Nestle good start

~Similac

All three I have lots of in both the powder form as well as the ready made form. What did you use for your newborn baby? Pros? Cons?
