Well, it looks like our child isn't arriving without some medical intervention.
Went to the hospital yesterday for another "how far along are we" exam, which Sue failed (i.e. it's not very far along).
At the same visit, Sue got booked in on Friday afternoon to be induced. Apparently, they do three attempts at inducing and if that doesn't work, they move onto Plan B.
I think Plan C is C-section, which involved up to six weeks recuperation, as it's major abdominal surgery. Thus, that's the very bottom of the desirable list.
Whatever happens, we've been assured that when Sue arrives at hospital on Friday, she won't be leaving without a baby, whether it's Saturday or Sunday when that comes.
It's all a bit final now and all a bit sterile and medical at the same time.
Oh well, at least we can see the light at the end of the tunnel now.
