Staci,
I have been watching periodically for Keegan photos. She is absolutely beautiful!

About the lump..... If it is somewhere around center to her belly then it is probably where her umbilical cord was. I can find both Dixie and Dusty's umbilical spot if I rub their bellies. It is about pea size and hard. If this is where Keegan's is then it is probably her umbilical cord "Button". Nothing to worry about.
