DS is 19mo, blonde-haired and blue-eyed and I suspect would burn very easily. We are off to Spain. Last year I was mega-paranoid abroad and had him slathered in factor 50, plus hat, sunshade on pram, threw a strop at DH if DS was in the sun for more than five seconds etc etc. He was only six months old and my PFB but I accept I was probably a bit excessive with it all. I'm not sure what to do this time - he is obviously very mobile now and will be running round everywhere, in the pool etc. Do I stick with the factor 50, or is there an argument for him needing a bit of vitamin D so I should maybe go down to factor 30? Thoughts please?
