Thanks everyone for all the good wishes and support. I did vaguely think that in a couple of months I need to pin them down on length of trial period, but wasn't sure about what would make sense. 2 weeks seems too short, as it did take her at least a couple weeks to acclimate to preschool; at least the 'drop off' part.
Re: onthegomom's comment about being so aware of this early on; it is a LOT easier to see the second time around! We definitely had ' damage' with #1, though we've dug ourselves out of that hole finally!
Lorel - very good thought about having some actual criteria for continuing ~ I think I'm going to check out the county site for what they might have available for 'k' prerequisites and end of year goals...
