Did daddy swing the baby with a bit too much strength while dancing? Did you notice baby couldn't move their arm and started to be fussy? Low and behold...it's probably Nursemaids Elbow.
At first I was really worried and kinda of upset. But thanks to the family docs who recommended performing a reduction, it was an easy cure. We bent Kai's elbow until his hand touched his shoulder and held his arm there for a minute. Then Kai began using the arm immediately. Only try this method if you are sure there is no fracture. If the reduction doesn't work, then head to the doctor's office ASAP.
