I hope I can remember this correctly..............You click on PROFILE at the top. It is in very tiny letters under your name. It should have a place where it says "MODIFY PROFILE", and you click on that. That section will give you all sorts of things you can do, but toward the end of it is a section that says "SIGNATURE". You can go into that section and add the info on your children and their ages. You can later go back and make changes to that area (like when your kids get a year older, etc). Try that, and let me know if it works. If not, hopefully I can help.
