Try it if you haven’t. I was advised by allergy specialist to bring Marcie for a swim and she’s a water baby! Pool water contains chlorine which may irritate the skin. I brought Marcie for her first swim at 9 months, bathed and moisturized her immediately. There’s no problem with her skin after every swim though she caught a cold twice!
I also heard from another talk by dermatologists that you may want to literally “test the waters” because your child’s skin may react differently in different pools, due to the different way of cleaning and treating the pool water. Other advice given in the forum (read my forum notes here) was to use SPF50 sunscreen, try not to go once the pool has been chlorinated nor before the pool is due to be clean (too strong chlorine or too much bacteria), always shower immediately and moisturize thereafter! Also good to find out cleaning schedule and the percentage of bacteria or amount of chlorine used.
