Honestly, I prefer arm floaties personally. I am sure some swim instructor will tell me that they dont help them learn to swim on their own, or that they are not cost guard approved for life saving, but that is not what I am looking for. I find life jackets, and even those that you found at Big lots, to be difficult for the kids to balance well in. I have 4 (almost 5) kids and arm floaties have worked for all of them! The oldest two swam at about 4 or 5, with no problems. And, of course, I am always right with my little ones with floaties on, but it gives me the extra assurance that we can all enjoy the pool as a family without worrying about them nonstop. By best advice is when you find the ones you like, buy several pair for each child. If/when you lose one, or it pops, they are nearly impossible to find again. I just bought about 5 pairs for my two youngest. I hope that helps..enjoy the pool!! ~A.~
