I don't know if you want one like that blue jacket, shewolf. Though it doesn't sound like Bean will be swimming in rough water (public pools around here get pretty rough though) you really want one with the neck thing because it is what keeps their face out of the water.
Quote:Infant/Child Life Jackets
An infant or child life jacket should have a crotch strap, which helps keep the life jacket on; an oversized float collar, which keeps the head out of the water; and a grab loop, which makes plucking a youngster out of the water easier

I think swimming lessons are VERY important but I do live in waterworld where even people who do know how to swim drown every day. The schools here have started offering free lessons to all second graders because there are still a lot of kids that don't know how to swim.
