In response to misslily's comment:
Thanks everyone for the suggestions. One of the books about feeding kids mentions the part about having them cook with you. I try when I can, but it's such a mess, and can be dangerous trying to watch 2 toddlers in the kitchen at the same time. We'll get there slowly I guess.
I didn't want to hijack MissLilys post, but I've actually been meaning to post this question about what to cook with kids. DD LOVES to cook and does it quite a bit, probably something every day (because it's easy when you have one and no distractions). We wash veggies together, and DH or I slice veggies and she assembles the salads (often in very funny ways). She helps me make french toast on the weekends, telling me all the ingredients we need and what the next steps are (I hope to be getting breakfast in bed by the time she's 7 :). I crack eggs into a cup and she pours them into the bowl, she adds cinnamon and nutmeg, tells me when we have enough milk and dips the bread, all relatively safe. The mixer when making cookies or cakes makes me nervous, but we do it. So does making meatballs or handling meat of any kind (which we don't), We try and include her with everything, and am just looking for new ideas.
What do you cook with your pre-schoolers?
