Not sure if the CC centres down there are like ours, but Natalie is attending a LDC centre and is in the Pre-school room where they run a government-regulated pre-school syllabus. It isn't mandatory yet but will be here as of next year. Even still, they have always run a kindergarten program, even for the 2-3yos (Natalie was taught numeracy, colours, shapes etc from the get-go!). So I consider Nat to be attending pre-school, even though the hours are longer than regular pre-schools. Phoebe by comparison is in the 'creche' room, where the focus is on creating as 'homey' an atmosphere as possible, even though they do already introduce the babies and toddlers to literacy and numeracy... the same way you would at home I guess.
Nat will have just turned 5 when she starts school (next year! EEEEEEEK!) but good ole Phoebs will be 5 and a half, just like CJ (to the date ).
If your CC is like mine, there's no reason to take her out of it. If she is happy and settled there and you are working and need the extra hours' care then why fix it when it ain't really broke?
