Thanks everyone.
Audax- I am not too sure, I guess 2.5 weeks after we get home. So DH and I get 2 weeks together with Bubs, and then I get a couple of days on my own with Bubs. Honestly, what is wrong with meeting your Grandchild at 2.5 weeks old? There wont be too much of a difference between the 1st day/2.5 weeks.

I do have a friend who iws in the same boat(all family interstate too) and she had them all organized to come when they thought she would go into Labour. Well, she went early, and she is glad she did in the end. She had that time to bond, and also go through the emotions the few days after having Bubs, without having to worry about people being there. I am thinking as the U/S shows us 1 week behind, at 6.5 weeks, I might tell them this is the date I have been given, and they should organize their flights over for 2 weeks after that at the earliest, so therefore they wont run the risk of me going 2 weeks late and then missing out. Thanks you all for your advice, I really appreciate it, and it's nice to know I am not a complete rude B*tch for wanting to do it this way.
