Our babe has very busy hands. She's big into cooking at the moment, although not all of it is edible. She's fond of making new recipes which involves taking anything that tickles her from the pantry and combining it with water. We've had spicy sauce to dip your chicken in, we've had cockorache soup and all sorts of unnamed delights. Of course they go in the fridge until bedtime and we eat them while she sleeps. In the morning we compliment her on their deliciousness.
A really easy, and edible recipe, is to make her a cup batch of bread dough (which I do almost daily) and she adds to it - coconut, hot chocolate powder, apple slices, lots of cinnamon. I don't consider all edible, but amazingly Ella eats them all, enthusiastically!
