My grandma's friend (who was a rural nurse back in the day) said that they used to tell ladies that when they could fit their hand (sideways, all fingers etc) between their bust and the top of their bump, they had 3 weeks to go before baby was born. When that happened, the ladies that were out on the farms (esp in the high country etc) were to make their way into town to wait for the baby to come.
Apparently it doesn't matter how you are carrying as the FH wouldn't be affected by the size of your bump etc.
So... try it out and then see if you pop in the next 3 weeks! When I was 1/5 engaged, I had 1 finger not able to fit. At 2/5 engaged, I could just about fit that finger in, and now baby has dropped even more and I can fit more than my blimmin hand there! Baby has to wait till 36w6d as her daddy is away
Would be interested to see what you all get

I'd never heard of it until now.
