For stay at home working moms, how do you keep your toddlers busy while you work and no one is available to look after them?

I keep my baby busy with the chores I am doing. Like if I'm cooking, I give him a container and spatula or a cup and plate to/bang on and play pretend cooking. If I am folding the laundry I keep him near me and give him his small baby clothes and he plays with it and tries to imitate me. When I am teaching my elder boys their lessons or homework I give the little fellow some crayons and paper and enjoy scribbling on it. Or sometimes I give him some puffed rice to eat and he is busy with it. Or the TV shows like Barney and Mickey Mouse really helps.
