Has anyone used contact detach sets during kindergarten. We are getting ready to start putting together a health plan for Abby. She will be entering kindergarten and insists on using the contact detach in her behind and refuses to try any other set. I am worried because last year she had one pull out in preschool when the tubing was pulled by another child accidentally and well they are very sharp. I have a fear she will somehow end up losing a set and another child will get stuck and people will flip out, etc. It's probably completely unjustified since that is the only set I have ever had pull out. Am I only one who has ever thought of this?
