Am I seeing double?

We were very excited to see Mike and Courtney's new arrival, Zane Michael while we were in Phoenix. He was born about 5 months after Jacob. I know that they will have a ton of fun playing together as they get older. Here is a picture of the two of them on the ground. Courtney and I would of had them closer but Jacob was swinging his arms too close to Zane's head. This is never a good way to start off a friendship.
