my recommendations...I have 3 kids and never travel w/o the following:
tums...kids can't take pepto, but they can take tums!
papaya tablets...for when the tums isn't enough. All natural...help the problem and you can take as many as you want!
not just alcohol wipes, but some liquid antiseptic or antiseptic wipes. Alcohol would really hurt if you wanted to clean out a boo boo.
lip balm with sunscreen. Believe it or not, this even came in invaluable in England in February! We were outside so much, and even on an overcast day you can get sunburned. The lips and eyelids are often areas that get overlooked, but boy do they hurt if they get sunburned!
also...keep your aloe gel/solarcane in the cooling box. It's amazing how good it feels on a sunburn when it's cold!
happy sailing!
