Sarah - i have a feeling ours was free, think it was a local gov one but i cant really remember. I am pretty sure there is a cost for the longer stays. I think Tweedle have a website maybe try and google it. I havent heard of the O'Connell one. A guy my husband knows through work did a week long one in Melb, i think it was at one of the hospitals? Anyway he swore by it, their baby started sleeping 12 hours at night and 2 one and half hour sleeps during the day. Personally i would jump at the chance if Lucas was a poor sleeper, it is one of the most important things in our house!!
