I don't think there is an actual solution to this, but if anyone has a crystal ball or possibly a Star Trek matter-transporter they aren't using l would be eternally grateful.
My daughter is expecting baby number 2 in a few weeks.
She lives in a different country to me - involves flying - about 5 hours door to door. This time around she would like me to be there with her (and her husband) for her home birth. I couldn't be happier as last time it was "no visitors for at least 2 weeks". A very lively and very lovely 2 year old makes that a little complicated this time 
So......I don't want to be doing a last-minute mad dash (I go there quite frequently and the plane is usually packed) but neither do I want to be intruding on them for 2 weeks or more - first grandchild was 2 weeks overdue.
Any clairvoyants out there suggestions? Light-hearted responses are totally fine as I realise that nobody can possibly know the answer.
