I moved DS1 from a child care centre with a pre-prep type set up to a proper pre-prep at a kindy. He knew no-one at the kindy, and his school is in another area as we moved and he also knew no-one when he started school. It made no difference whatsoever that he knew no-one.

Every child is different so you are the best person to make the decision. However for my boys, the proper pre-prep suited them better even though they liked day care because they were ready for something new and different routines and challenges.

I should also add that there is probably no wrong decision here. I am sure whichever way you go will work out really well so try not to worry and just trust your gutt.
