Did I mention yet just how little research there is on this topic? When Dr. Volling searched for research publications to include in her review, she found only 23 published studies and 7 unpublished studies (like doctoral dissertations) that met her criteria. In the past 14 years, only one study has been published on this topic! One! Isn’t that crazy? Think of the million of kids who go through this very common experience every year, and yet little to no research is being done to understand kids’ reactions or how to ensure it is a smooth transition.
