My 2 labours got shorter. #1DD started mild contractions at 10am Sat and she was born at 1.35am.
#2 DS started mild contractions at 7.30pm and he was born at 4.36am. Actually delivery for him was 6 minutes apparently. That was quick.

Doesnt it depend how firm you are inside again from previouse pgncy? Thats what holds it all so when the time comes, if there isnt much muscle to hold bub back then look out. Correct me if im wrong. Sounds logical that all.

I can totally understand your apprehension (s) about it all. Is there any chance your mother could come stay with you when you are nearly full term. Just a thought. Your Dh may want to throttle me for that suggestion .
