I have always made sure that I applied sunscreen on my children when they went outside and thought I was doing a great job. But earlier this year my nine year old daughter was diagnosed with early stages of skin cancer. So protecting her from the sun has become even more important. We recently start using Coppertone Kids continuous spray with a SPF of 50. It also is broad spectrum and has UVA and UVB protection. It is also waterproof and hypoallergenic it goes on clear so I don't have to worry about it getting on my kid's clothes. It lasts for a good amount of time and has always done a fantastic job of protecting them.
One of my favorite things about it is that it is a spray. It sprays at every angle which helps me make sure that I get every part of her skin even the hard to reach places. It also doesn't take as long for me to put the sunscreen on my kids. Also with it being a spray it is easier to get even coverage. It has a locking twist lid so you don't have to worry about it accidently spraying in your purse or beach bag.
The only drawback to this is that with it being a spray you can't spray it directly on to their faces. The directions say to spray it on your hands then put it on their face which I have done and it has worked fine. I normally carry a small bottle of regular Coppertone sunscreen in my purse and use that for their faces.
