We're going to Florida for 4th of July to visit some friends (Hollywood/Fort Lauderdale area), and planning to spend time at the beach there. My 4 year old loves playing in the sand more than anything and we already do sunscreen and staying out of the sun in peak hours, but I want to be mindful of the much stronger sun/heat than what she's used to. My friend sent me a picture of her son and he's in a full body rash guard, so I'm wondering if I need to get more coverage for my kid as well, but don't want her to overheat either (and she's very prone to overheating). She's got darker skin so she doesn't burn easily so I'd love some tips on what works well. Thanks!
