having just given birth to a gorgeous 5 day old, i am wondering how on earth i will cope with my energetic 2y.o. once hubby goes back to work next week.... any tips from those who know?

one of the options i have thought about is to get an au-pair (live-in)....
-can anyone recommend a website
- or an au-pair, who is available to work now in the south-eastern suburbs of melbourne
- what is the going rate for an au-pair: any tips on doing my research re: what to look for, etc etc

thanks kindly for any input!!
