Accidental injury

Anybody ever accidentally injure their kiddo? My 5 year old was helping in the kitchen tonight wanting to help cut some carrots, we had just bought her the kids knife from ikea and she wanted to try it. I was showing her how to cut the carrots and her little finger got under the blade😭. I feel horrible, it’s not deep, we cleaned it up and put some dermabond (medical grade skin glue) and then a Bandaid. She’s fine but I still feel like I’m the worst parent ever.
