My white MacBook was in the same boat. I still use it as a media computer, so I formatted and installed Ubuntu Mate 15.04. If your son is just using the web browser, I doubt he'll notice the difference in OSes. I don't know how old he is, but it could be a fun weekend project for you guys.

If it were just the web browser I would have probably moved him to some incarnation of Ubuntu. Unfortunately, when it comes to applications like Photo Booth that are easily approachable by a 6 year old the situation becomes more complicated.
