I took one look at it and agreed that a trip to ER was in order. It took a total of 42 stitches to sew him back up and the doctor said that it put his skills to the test. An artery was cut, but fortunately no tendons. He is now sporting a hand immobilizer that he is supposed to wear for the next 10 days at least.
At the time the accident occurred a friend was here helping install the fencing , so she stayed and watched the children (and finished the fencing job) until my mom could come and get them. Needless to say it was quite the day!
