Asking Questions Instead of Making Statements...

That is what Robyn (4) has not been doing. She will state something instead of asking, at first it was funny and now it is just annoying. She will say something like, "Santa is bringing me a barbie!" instead of asking something like, "Is Santa bringing me a Barbie for Christmas?" She is so certain and states her case with such conviction, I don't know what I am going to do!
