Yeah, grandkids can be dangerous. A couple years ago at the end of a long Christmas Day my two oldest DGS's, then about 12 & 14 decided they would hug me, one in front and one behind. They hugged me so hard they broke a rib; I was in pain for weeks. They thought I was joking when I said, " Oh, you just broke my rib!" Now they hug me very carefully and joke about it. I hope your lip is getting better fast.
