Hi
welcome to the forum
this was discussed a few days back, or was it weeks.. anyway, i think the thread was child birth cost or pregnancy cost.. search the forum with different key words, i am sure you will get your answer in the thread.
secondly, if u do plan to have the baby is your own country, you will have to get a passport for the baby once she/he is born, after that apply fro the visa, it normally takes a couple of months if u have a visa already. A friend did that and managed to be in AU 2-3 months post delivery.
They do a medical on the baby but nothing big, no xrays, just a regular checkup.
you can either go, have the baby there or you can go and validate it in her initial pregnancy days, I think a lot of airlines do not allow pregnant women to travel in last couple of months.
And dont be so confused or in a surprised state.. pregnancy is a beautiful exp, a gift of god (though its u who does all the big tasks of growing, managing the baby, having a secure pregnancy
)
Enjoy it..
Hope this helps. I am sure someone else will add to what I suggested
Cheers
