Not sure if Max is your first as Sophia is our first. We have been taking her to the YMCA to get her aclimated to water and it was great watching her figure it out. We live on the Mississippi river and are big boaters. Our friends take their children out at a very young age and this would be Sophia's first summer out on the water.....however I can't help but feel very apprehensive about this which I thought I would never be this way. I guess one step at a time for the parents too. I think it's great that you are getting him so used to the water so early. Good luch with snorkeling by age 3.
