Just adressing the FB issue and being his friend: I really think it is a good idea. I also spend a lot of time in their room since that is where my computer is(that's another story). It has allowed me access to the kids, their friends and they don't seem to mind. They talk about almost everything in front of me and come to me when they have questions or need help. FB fills in the gaps. I even have some of his friends calling me Mom!
