Hi am going to Majorca in 6 weeks time and have no idea how much to take. My boys are aged 7 and 10 years. My partner seems to think two bottles will be fine. Personally i think his dreà ming. I so far have 6 bottles of factor 50+ as i will not use anything lower (my kids are fair skinned and even with this hourly burnt in Cape Verde). I was wondering if this is enough for a week if i get one more 200ml bottle that is meant to last 3 hours in water. Im aware kids will be in and out the pool using lots of cream but thought if i use the extra water resistant ones early morning until lunch and from about 2pm and use the 3 hour water one to cover the hottest time of day if i csnt keep tgem in the shade. Will 7 bottles of 200ml last 4 ppl for a week or should i pick up any more. Any advice greatly appreciated.
