DD (3) has come up in a rash from using sun cream this week. I do keep her covered with hat/long sleeves etc but want to use cream as well for full days out/beach etc. I think I just need to trial and error different brands etc but it's going to cost a fortune potentially if I have to buy more than a couple more brands. Anyone have any tips on any that are particularly good for sensitive skin? She doesn't have any skin conditions normally. The one I started with is boots own brand kids sensitive 50+ spf.
