With those who has no1 and intend to put to cc, it is better to start beginning of this year to adjust them to cc life.
I have put my no1 to cc from last year may, she started the cc half day for year 2013. And this year jan'14 i transit her to full day quite easily.
It will def make the transition period easy if they have started early, as they have known some friends and the teachers there well. Im glad i have make such arrangement so as not to stress myself for no2 and the transition period for no1. Of course initially we tends to be bu she , but look on the brighter side, they do make friends, learn new things rather than staying home and do nothing.
