Ooops, he did it again

I arrived home from work on Wed. night and was greeted by Tanner laying on the couch. Reed said he just woke up, so that was why he was laying on the couch. His face was scuffed up, apparently he did a face plant in the sand at the park with the babysitter (he was doing superman on the swing and lost his balance) and because of the way he was laying I asked what happened to his arm. He had found Heidi's "fancy Nancy" stamp and put it all over his arm, which was the explanation, but I should have done more follow up on that one. So I set into making dinner, get it all done, the girls sit down and Reed asks Tanner if he wants to come and eat. He won't move. I look at him and realize that his right arm has not left the spot where he was gripping his left arm since I looked at him 35 min earlier. I instantly knew that there was a problem. Tanner has dislocated his left elbow on two previous occasions. We tried to quiz the girls on events of the day to try and decide when this happened. We call the babysitter, who only said that he was sleeping in a funny position for his nap. Turns out the girls were cleaning their room and Tanner was messing it up. Zoe was trying to get him out and pulled him by the arm. This must have been just before Tanner went down for a nap. So I pick up Tanner and his blanket and we head to the urgent care. After waiting for an hour and a half the doctor walks in, says, "you have done it again", pops it back in and we are out the door. The good news is that the ligaments are getting tighter and he will grow out of this soon. Hopefully.
