Not sure if this has come up yet, but my father has a boat and they like to hang out on it while docked. I'd like to take DS on the boat without going out, but not without someone kind of life vest or floating swimsuit but I can't seem to find any online for babies under 12 months, they are all for toddlers. Anyone know where I can find them? Or if they even make them for a 7 month old? Thanks!
