yep unfortunately you cant do anything until the baby is actually born.

you can of course start to negotiate now, but even if you two agree on something, the court cant make it official until there is an actual child!

So your options once the baby is born are:

If you two can come to an agreement, you can file an application for consent orders with the court, as long as the court thinks the orders you have agreed to are fair they will seal them and they are binding court orders. This should take about 2-4 weeks from when you lodge the documents.

if you cant agree to something you will have to go to court. To be able to file an application with the court though you have to file a certificate that you have attempted mediation. You can do this at a government run family relationships centre which is free, but the wait is about 6-8 weeks. Or you can go to a private counsellor who will charge anywhere from $200-$400 per hour. If you both participate and cant reach agreement they will give you the certificate. If you go and the other party doesnt respond/refuses to participate they will still give you a certificate. You then file your application with the court. It will take 6-8 weeks to get your first court date and on that date not much will happen anyway, they might make some interim orders which are usually fairly basic and general and with a newborn I cant imagine they will give dad more than 2-4 hours, 2-3 times a week to start with and it will get adjourned for another 6-8 weeks at least.

hope that helps!
