Yesterday the nurse noticed that his left arm was swollen and was in pain upon movement. So we spent 4 hours in the ER getting X-rays. His elbow got dislocated somehow so they put a splint on and referred us to an orthopedist Dr.
I feel really bad because we don't know how it happened. I also have very good nurses who are careful with him. We suspect that he may have gotten his arm or wrist caught in the crib slats and then he tends to do flips in his bed. He's not in pain anymore since having the splint and some ibuprofen.
