Comotomo or mam?

Amanda • 22. Married 💍. 3 year old son. Due with baby #2 July 5th 2016.
My EBF baby will not take the bottles I have tried. The brands we've tried are tomme tippe, avent natural, and munchkin latch. I'm trying to find a good bottle because I will be starting work soon and I want him familiar with it before he starts daycare. I've seen people's say Dr. Browns if your EBF baby uses those do you buy the wide neck or regular? I want to try Mam and comotomo as well. Reviews on any of these. He's almost 2 months old and I want him to transition from bottle to breast easily while still wanting to breastfeed when at home.
