My family swims at the YMCA, and I had been informed my 3 year old''s floaty swimsuit was not allowed because it wasn''t US Coast Guard approved.  I got online to find a suit that was USCG approved and it turns out there are VERY few, most things you find are just life jackets.  However, you guys had this cute little suit that was very similar to what he had been wearing, but was also USCG approved!  It also keeps him a couple more inches higher in the water than his last suit, so he doesn''t accidentally drink as much pool water.
