When my daughter was 5 she broke her wrist rollerskating with her aunt. This was around 5 pm. She came home around 9pm after visiting with her aunt for the day. She did not cry, or act like it even hurt ...same as in the article. It was not until the next day that her arm swelled and became bruised. We took her to ER and it was a horrible fracture. One bone literally went into another in which pins and surgery took place. She never cried, (except when she first fell according to her aunt) and nothing appeared to be "hurt" until the next day and the obvious swelling/bruising.
