floatable armbands

One of our sons does not dare to swim without those special floatable armbands when he is not swimming in our own pool. Although other pools have the same depth he wants to wear his armbands. It is something in his head that he is not feeling safe in another pool. In our own pool he swims like a fish and always without floatable armbands. Today there were a lot of friends also from school in the swimming pool of our neighbors and our son was hesitating to wear or not to wear his armbands. After a minute he decided not to wear the armbands. This was a great progress.
