Stephen was feeding his wife, who was still in bed. Of the three, only his wife remained in bed. Her injuries were severe. If she hadn't tried so hard to protect her son, she wouldn't have been hurt. Her attempt to help made no difference to the outcome; instead, it only worsened her own situation.
