Today I happened upon DD during recess after discussing some thing with the aftercare staff (I swear I wasn't spying - pure happenstance!) DD hugged me, sighed "mama, it's SO great here", demanded a kiss and ran off to play.
And everyone connected to the school I mention the classroom situation to (both size and split), upon hearing the name of the teacher, confidently says "that'll work".
So, exhale. The last issue remaining, will this force our hands next academic year, will just have to wait. I'll, um, just not think about it for the moment, or worry, or think ahead to middle school or anything...
