Help! My little guy (5yo) is super skinny and gets so cold his lips turn blue during swimming lessons. The pool is around 30 degrees and he wears a shortie neoprene suit already - has anyone tried the long legs/sleeve one for lessons? My concern is that they're so bulky he wont actually be able to move... I'm running out of ideas, having tried thermals and neoprene now.
Anyone have any ideas what else I could try?
