I am a bit late to the party here with a comment, but we have two nurses here (MS, 900 plus students) and last year we saw...brace yourselves...150 students a day. Yowza...the other nurse has been here quite some time and she would put out an entire snack buffet for the kids, she had closets full of clothing, she would let them come in and fix hair and/or make up, she would let them come in and JUST. SIT. AND. TALK. Not a student in crisis who needed counseling, mind you, but just come in and visit.
Well by June I had enough and had come to the conclusion that what I was doing wasn't nursing, so I left the job. Circumstances are such that I find myself long-term subbing in the same school, in the other nurse's position, and the new nurse's mentor came in and absolutely demolished the clothing and shoe stash, and is teaching the new nurse not to feed them, not to give them mints or cough drops or lip balm or bottles of water...we see maybe 30 a day of legit health problems.
And this new nurse is AMAZING and we work well together and I am so so sad that I am but a sub and will have to move on eventually but that is another story for another thread. The point here is, they are like cats. If you offer food and clothing, they will show up in droves. If you just get rid of stuff like clothes and shoes and your answer every time is "I don't have any", they will stop showing up and you can focus on actual nursing.
The teachers are slowly getting the message. Patience.
