Quoting Tiger Lily ♥:" you just need to be sure that any sort of knife is put up and away ALWAYS."
Because she doesn't feel bad enough already.
OP, I was once cutting up a kiwi, and I didn't think my son could climb things yet. I saw it was about to rain, and we have a little portable clothes line that I can hang up on our porch to dry clothes. Well, I ran out to unclip it, and was right back inside...30 seconds? I come back in to see my son crying, and holding his hand. I thought that maybe my daughter has taken something from him. I asked her what happened and she said, "He grabbed your knife, so I took it out of his hands..." I panicked!! He has cut inbetween his fingers from her pulling it away. I quickly packed us up and we went to his doctor where he had liquid stitches. I felt like the worst mother, ever!! Sometimes things happen though, you live and learn!
