floaties do one think they have a website otherwise debenhams stock some stuff also check out ebay some may be for sale on that. i had what looks like a life jacket for my grandson from there range when my grandson was small and that worked great. also the wet suits they are selling every where at the moment in supermarkets make you everso boyant so if you can get one of these that small it would double up by keeping them warm as well with extra protection of using arm bands .they also did do swim suits with floats in them you take out as they get more conviedent but to be honest they would proberley grow out of them before that.
