Well #2 started school today, obviously the experience is all shiny and new at this point, but so far so good. And I have yet to find time to write a letter. I will sit on it a bit longer. But at some point I am going to have to either write, talk to them or find a new preschool. Of course finding a new preschool for #3 would require then explaining to the principle why I am cancelling #3's enrollment in preschool but not school. The issue can't really be avoided, not permanently, but I have plenty of time to procrastinate :-).

Actually, the issue may be avoided by a possible move interstate forcing a complete school change. So there's that.
