Hi David

You are brave to step into our parlour !

I'm not in here often so feel like a bit of an intruder too. I've been kicked off for trying to help people find information a few times so will attempt to help without breaching the regs.

suggest your sister or yourself if you feel like it does an internet search using terms like :

Lesbian Parents Australia

same sex families

lesbian families

lesbian conception

There are also groups on yahoo.

There is a wealth of information out there and your sister and her partner need to do some research so they can get a better picture of which way they might want to go about becoming parents and then they will start to have some specific questions to ask .

Best of luck
