Yeah, well, since it involves Kevin and tools, it could be fun or disastrous. He has a tendency to try to cut off his fingers, so I have to watch him carefully. Ofcourse, you know how to fix fingers, right? Duct tape. Yeah, that's the ticket.
I had forgotten about the push-me-pull-you! My son (5yo) loves Llama's too. He thinks llama is a funny word (he's right) and he calls me Mama Llama. I may have to try to make one of these as well! Great idea!
