I loved this article about ways to include our children in the kitchen [1]. You all should know by now how exciting it is to me to be able to include my little ones in more and more of our day-to-day doings, and yes -- a lot of our day is spent in the kitchen! :)
I mentioned once that Eliyahu keeps taking Yehoshua's jobs. Here are some of Yehoshua's newer jobs:

I use this weekly vitamin dispenser, so that I only have to open my vitamin bottles once a week and not daily. I have been having Yehoshua sort and fill the dispenser for me. Of course, I supervise him the entire time he does this, since I don't want him to eat any, or drop any on the floor for Eliyahu to find. :)

Another job that requires close supervision, but is oh-so-fun for a 3-year-old boy: using a screw driver to tighten the handles on my pans. That has always been a bothersome/neglected job in my kitchen, so it's quite handy to have a helper to do it for me! :)
The article I mentioned above gave me a few new ideas for Yehoshua. Ziplock bags, greasing pans, and washing dishes... those should be fun projects to learn! :)
