I dont make my boys wear sunscreen UNLESS they are going boating. The reflected sun is many more times the exposure of direct sunlight.

My boys go shirtless as often as possible---hoping to prevent ricketts, have strong bones, and hopefully miss the cancer.

My mother used UV treatments for a skin condition per her specialist. Exposure all winter long in a homemade suncabinet, laying out in the sun from early spring into fall...and yet she did not get melanoma cancer or any other skin cancer until her late 70's. I dont think this is a fluke. I truely credited her great diet and living in the clean fresh air of Maine for the prevention. By all accounts and the viiification of sun exposure causing cancer, she should have had skin cancer by her 40's....but didnt. Makes one think......
