Jan, I think the reason that 2 days a week works better is because for a littlie, 7 days between kindy days is a long, long time. So it doesn't feel like such a regular thing, and there is so much time in between they don't remember the routines etc so well. Twice a week just gives them a bit more familiarity in the new environment so they get used to it more quickly. Mind you, one a day a week is probably easier on the mummy LOL!!
