My 2 year old helped me with all my baking as well. I would bring her little table and chairs into the kitchen and we would measure or weigh each ingrediant separately to create a mise en place, making sure that there was never anything extra on the table that would distract her. For example, when it was time to measure the flour, I would take the flour, the scale, a spoon and a bowl and put it on the table. I would let her help me spoon the flour into the bowl and have her try to read the numbers. Once we had enough, I would put away the flour, and the scale, and set the measured flour on the counter. Then, I would give her a towel, she would clean, and then we would start with the next ingrediant. Once all the ingrediants were measured, she would help me pour together and mix. If it was cupcakes, I would ask her to hold down the cupcake holders while I poured in the batter. It takes about 4 times a long this way, but it is one of her favorite activities and the whole thing is a math lesson (in addition to, of course, being a lesson in how to make good baked goods!).
