Well, the short answer is that we'll probably have to stay with whatever we decide for at least a year. The Montessori school fills quickly, so that would be a no-go if teaching her in my own classroom didn't work out. We could still enroll her in our neighborhood school, but they only have 1/2 day kindergarten so we'd be scrambling trying to find quality afternoon child care (the good places fill early). So we'll probably need to stick with our first choice, whatever it is....right now, I am leaning toward taking her with me - but we'll see what I think of things after I meet the reg. ed. K teachers at the end of next month.
There is also the possibility of staying in my current position (teaching science) and getting her into the dual language magnet school nearby. I've been reading good things about language immersion on this board, and that is an option for us well.
So many choices!!
