I think the cost of 3yo kinder varies from region to region. Down this it costs about the same as occasional care, so about $7 per hour. I also wondered about whether to use 3yo kinder or continue with 1 day per week childcare. We stuck with the day per week childcare. Cost wise it was better value, plus for both DD1's and my sanity we both needed more than a 1/2 day. Also I spoke to a number of people who worked in the childcare/kinder area and they all agreed there was no need for 3yo kinder if the child was in some for of childcare.
