It sounds like Tanya is equally lucky to have you. My mom's sister had two boys and always wanted a daughter (plus I was the only girl on their side of the family) so I was essentially blessed with "two mothers" and a doting grandmother :o)
Well, we sure feel lucky to have her (and her mom) in our family. Tanya is 16, but is refreshingly unsophisticated, if you know what I mean. She enjoys being a kid and I think that is a good thing. Most kids today are growing way too fast.
Sounds like you were blessed with lots of love in your life. Can't have too many doting mother/grandmother types in your family, I say. :-)
