I have a few that have been here +20 closer to 30 times already.
I'm at the point where I just have them call their parents (if they're old enough) then I talk afterwards if they want to speak to me - they usually don't.
I had one 1st grader come to me 7 times in one day - various complaints (stuffy nose, hit finger on desk, paper cut, etc...) I went to the teacher and asked what was going on - she didn't want to deny him going to the nurse, okay fine but 7 times in one day! He's on my automatic call list.
I have several littles that will become incontinent when they don't want to be in class and one that likes to vomit so he can go home.
Brother and sister in competition to see who can see me the most in one year. Bonus points for phone calls home. Mom actually told me about this competition.
I have several kids on different plans to try to decrease the amount of visits to me. I have spoken with the Principal, Teachers, and Parents. I try to get everyone onboard. These kids are here to learn, not sit in my office doing nothing/playing.
Trust me my office is not fun, I hide the books and anything they can play with because I don't want my office to be a hang out spot or somewhere to play. If you're sick, you're sick - no playing. Peeing on yourself on purpose is not okay and I will not reward you by giving you fun things to do in here while we wait for Mom to bring clothes - some parents just won't bring extra clothing, grrr.
I had one kid ask me why I didn't have a TV because my office was so boring, lol.
