cooking with kids

Daniel is at the point where he has to be a part of everything mom and dad do. With that in mind, we got some Christmas toys that are more like parent-and-child projects. Right now, Daniel and Chris are building a new train table, complete with tracks that run up a mountain and beside a lake for all the boy's trains. They've had fun laying it out and tinkering with the design, but Daniel's ready to play on it! Also on tap for father and son: the Craftsman "My first engine." We found it while rambling through Wal-Mart a few months ago, and it's got almost as many pieces as a real 427. The question is, how many will be left over when they're done ans it's running?
