Muffin Cup Anyone?

Katelyn rediscovered her muffin cups at Grammy and Poppy's house a couple of weeks ago and she still loves them. What a cheap, durable toy! I just bought them because she could chew on them and eventually stack them, but they have coaxed her to creep, crawl and cruise so far. If they work for potty training, I am writing a book about the wonder of these things : )
