Query: I might have a "defective" Pooh.

We gave this to our 21 month old on Christmas morning. It worked well in the box and she was quite delighted with it. However, Pooh will stop walking in mid-stride and will not turn back on for hours. I have already changed the batteries once--15 minutes after taking it out of its box. When he does walk, he doesn't go very far. It's a shame because she seems to like him and wants to cuddle him all the time. I might bring him back to the store for an exchange. Maybe we just received a "defective" Pooh.
