We're going to Mallorca next week and have a villa wirh a lovely looking pool. But it's suddenly occurred to me it may be too cold to swim in! Dc are 4 and 2 and not keen on cold water, as I'm not. Are wetsuits worth it to make it bearable?? Anyone swum at this time of year? Now wishing we'd not bothered with a pool as I'll worry they'll fall in without even being able to use it!
