Personally, I have yet to try swimming because I'm afraid it will be akin to polar dipping. E has gone in a few times. Unfortunately kids are not a great gauge for water temperature, they seem to be immune to cold when it comes to swimming! Do you remember being like that as a child? It didn't matter if the water was cool & refreshing, lukewarm or about to give you hypothermia - we'd all just keep swimming (teeth chartering & all!) until a parent forced us to warm up for awhile.
Great, I'm pretty sure I'm one of those parents now....."C'mon E, the water's pretty cold, sit here & warm up awhile!". When did this happen???
Anyway, in the spirit of summer and beach lovers everywhere, here is one of my favourite LO's of a day at the beach a few years ago. Enjoy!
