feeding question from a new dad?

Your not "cutting corners" at all! You are doing the two most important things 1. He is getting milk and 2. He is nursing most of the time which is an important bonding experience. If she pumps than you can bottle feed as well and bond with him to. My husband loved to bottle feed when I would pump and I loved that he got to share the sleepless nights with me. : ) Good luck with your new born.
