You need to work through a few scenarios and then take the appropriate action:
e.g.
1) if you got your visas at the end of January and visa states you must arrive by say July 2006, will you be migrating to Australia before baby is born and would you remain in Australia for the birth ?
2) If you want baby to be born in your home country, have you got time to sort medical for baby and add to your application before the July travel date and then you all validate before the initial entry date ?
3) If you do not want to travel to Australia before the birth and say baby is not due until June-July, you all need to do new medical clearances at the same time that baby does, and also renew police clearances.
First scenario does not need any notification to ASPC. 2nd and 3rd Scenarios need immediate notification to ASPC asking them not to grant your visas until after the birth of your child.
So you need to work through the possibilities of when you get your visas and what would be your plan in each case.
