I seem to be the odd man out here but I use bug spray and sunscreen. I have only used sunscreen on their faces one day last week when we finally had some sun. Our group spends a great deal of time outside. We spend 3 or more hours a day outside and as much as I try to keep the kids in the shade they love to run and play in the sun. I also have some very fair skinned little ones too. I get the parents to give me $10 every spring to cover the cost of bug spray/sunscreen for the season. If the bugs are bad I put bug spray on. I buy the family kind. We also have the mosquito magnet (propane tank one) in our yard to help.
