I had a video of M from 4 years ago mixing up some cookies. As she mixes them she starts to sing "I'm making cookies, all by myself. I'm not needing help! No...." It's an awesome video.
Today M made a batch of cookies, using a recipe! I never use recipes and the kids understand that that isn't actually a good thing. Or so dad gently prods... The recipe was gigantic so we had to divide it by 4. M did all the calculations. I had to help her with dividing 5 cups by 4. She got impatient and said "We just need to make them!" I informed her that if she wasn't going to learn, she wasn't going to make cookies.
They were really good.
We have a cooking station set up now for the kids. It's pretty awesome.
