My kids are 4 and 6 and they regularly put cereal into a bowl and pour milk over it. It's nice because if no one is around to make them breakfast, they just have cereal and we can sleep in a bit more. Of course though, it goes without saying that they put in more milk and cereal than they need into the bowl! Working on that part...

I was probably around the same age when I started making myself a bowl of cereal...

When did your kids (or you) start making breakfast on your own?
