Going on holiday abroad for the first time as a family in the summer. I am unsure whether to buy my 2DS (4yrs and 8 yrs) UV suits. Don't want to waste my money if they don't end up wearing them. Will they end up just wearing shorts and no top? Surely sun cream will protect in the same way the suits do? As a child I only wore shorts/swim costume abroad and it never did me any harm. Does anyone recommend UV suits or are they a waste? What do others put their DC in on holiday?
