Alexa and Carlos PenaVega's middle child is on the mend after a terrifying injury. The actress revealed in a lengthy post on her Instagram story this week that her 2-year-old son Kingston severed part of his finger in a recent accident at home. Alexa explained that she shut the little one's fingers in the hinge of the bathroom door and it was "the most traumatic thing" their family has gone through, but luckily the toddler is already making a full recovery.
