Indian Giver

Ryan and I have had several rounds of 'Here ya go.'-'Thank you.'-'You're welcome' the past few days. Our little game goes kind of like this:
Ryan brings something, a book for example, over to me and says,"hee ya oh."
I take the book and say "Thank you."
Then he puts his hand out and I give the book back and say, "Here ya go."
Ryan says, "takoo."
Mommy says, "You're welcome."
Repeat as many times as Ryan thinks it's fun. Usually he ends up with the book(or whatever else) in the end.
