I use Desitin for sun protection and chafing if I'm going to be in the water over 4 hours, but otherwise, Aquaphor or Vaseline work well for chafing with much less mess. If you go with Desitin, bring baby oil (your toddler can probably spare a bit of that, too) and a cheap wash cloth to get it off. Ponds Cold Cream works, too. Enjoy your swim!
