Last night my 5 year old, 3 year old, and 9 year old used actual sharp knives to help me cut up a potato. Before you can child protective services, I was right there helping, guiding, teaching them how to slide their fingers back out of the way.
No one died. No one even bled. No tears.
Kids are smarter than we give them credit for. Let them learn. Let them explore. Believe in them.
