Third babies are notorious for being naughty about being born! Mine was 12 days late, my midwife did about 3 sweeps, but when I was actually in labour she didn't believe me for ages because of all the false alarms !
Visualisation is good, as are aromatherapy oils, I'm not qualified, but I'm sure you could ask on MN for advice.
I made my dh have vigorous and frequent sex with me, in positions guaranteed to get the good stuff close to my posterior cervix. Good orgasms set of BH as well, which might tip you over into the real thing.
Good luck,it is miserable being pg and looking after children at the same time. You can't go out, can't stay in, can't stay awake or go to sleep!!!!!!
It's only tuesday, friday is still quite a long way off, so fingers crossed!
I had dd1 in hosp, dd2, dd3 and dd4 at home, much nicer!
