If you let your kids do crafts, they will eventually start without you one morning.
If you let your kids use tools, like scissors and hole punches, they will learn to cut.
You will also sweep up a mess like this at least once or twice a day.
You will probably also end up eating breakfast mid-project.
But, they will ask you for playdoh instead of TV...
And they will amaze you with what they can do all on their own.
