I don't know if she was 5 at Bilbo's party...I dunno where that came from! Years did pass by after....Actually 9 to be exact, between Gandalf riding to Minas Tirith to find out about the ring, and returning to get Frodo out of the Shire!....Then 1 year was what it took Frodo to get to Mordor.....So I guess it could be! I think she must have been a little bit older.... 😕
