I just wanted to share my amazing experience with you all and encourage anyone that was considering swim lessons for their baby to do it! My little guy loved it and apparently when they are this young holding their breath comes naturally still from being in the womb, so you don't really have to teach them. Our local swim school gives free lessons to babies under 4 months for this reason, it makes future swim lessons so much easier if you start then this young. The objective is to teach them to roll over in the water and float.
