During the summer months my kids and wife LIVEat the pool. Between swim lessons (2 weeks straight every other 2-week period), family swim nights (Mondays and Wednesdays), and other occassional visits, my children spend so much time at the pool that things start changing color.
Their hair gets so much lighter and their skin (in parts) gets so much darker.
So without further ado, here are some comparison pictures (of the girls ... the boys will come later), with the last picture in the chain being VERY worth you while as it is the most extreme suntan line I have EVER seen! Enjoy!

And here is Brooklyn (7) ...
And, arguably, the BEST for last ... Catalina (4) ... and her ghost face tan line! :)
