D.S.
I have never in my life heard of such a thing. I own a childcare and in all of my years doing this I have only had to suspend two children. One was a kindergarten child intentionally urinating all over another boy soaking his clothing (we do not stay in the bathroom for kindergarten children but right outside the restroom to allow privacy) The second was a child who after repeated conversations about violent outbursts,the child bit and hit a teacher. To me a three year old urinating, not having perfect aim, and being suspended is crazy to me. First of all most three year old children are learning how to use the potty, and how to aim. If he did it on purpose or to be funny then you should have received a phone call to discuss ways you can work with them on stopping him. As far as the tile coming up, my husband almost had to use a jack hammer to get up my bathroom tile when we remodeled my bathroom. I doubt a little urine a few times a day could ever loosen tile. I would never put a note in someones mailbox with such a strong message. I would have called the parents and asked for a meeting, and went from there. I think you should start looking for a new center, one with better communication policies in order and much more professional. Also, have you signed an expulsion policy stating reasons why your child could be asked to leave the school, or be suspended. If not then check you school policy handbook, it should clearly state reasons why a child could be asked to leave a center or suspended, I am sure urinating on the floor is not listed.
