Share 'Password Problem'

I was very happy to find Glubble on Firefox. I thought I had set up everything correctly and had no problems adding the kids, etc. My problem is everytime I am in the main page and try to do anything I get a pop-up box asking me to have a helper put in the family password. What have I messed up? I thought as the mom I could move about easily on the site but it looks like it thinks I'm a kid?
