i have one, but only by fluke, ds found it in the 20c toy biun at the op shop, had no idea till i googled to see what everyone was on about with "sophie"
it causes more fights then abnything to, theuy all want to play with it, and the dog wants to eat her when the squeak is set off
yet to see results as a teether, but it has been a good dummy substitute for dd2
Score!!
