Where are you titchy tiny, itsy bitsy, teeny weeny tiny teddy (Anna)

Why is that Emma's favourite stuffie - who must be found before bedtime - is "tiny teddy", who is only about two inches long. Life would be so much simpler if her favourite toy was "big teddy", who is much more easily found and doesn't have the same tendency to go off on adventures into the deep, dark recesses of the couch.
