Always best to take whatever factor you need with you ,it cost a lot more over there ,especially high factor for kids/babies ,my daughter run out for my year old grandson a few years ago it cost her £17 from a pharmacy
Just got rash vests for my two from Tchibo today- £7.99 and nice quality. Normally we just use t shirts, but as recommended by HT members these seem like a good idea as they don't soak up the water so much.
