A great little idea care of the Teach Pre-school blog - Rainbow Toast. This is particularly ideal if you're persuading a reluctant child to eat their breakfast, though you might be creating a rod for your own back as it could be demanded at all breakfasts there on after. At least they'll be eating.
To give this a go simply pour four or five small cups of milk and add a different food colour to each. Get hold of some clean paintbrushes and get the kids to paint the bread before putting it in the toaster. Butter up and tuck in.
