apparently massaging the webbing between your thumb and 1st finger works (acupressure point).

Nipple stimulation - only one at a time though as 2 causes foetal distress.

acupuncture

and eating a whole pineapple - i'm dubious about this one though - my sister told me this one and i wouldn't put it past her to tell me just to see if i'd do it LOL

good luck hun. i've been trying hard to naturally induce labour also with not a lot of success - DTD tends to quieten things down LOL. but am keeping at it just in case.
I hope our babies will decide to show up before we run out of ideas! I just got out from my shower and I've been trying the nipple stimulation. My breasts are a little engorged at the moment so it took like forever to stimulate my nipples. Well, at least expressing some of the colostrum out made my breasts feel less engorged. Aside from that, no contractions yet.

Tonight, I will just have to make DH work harder in hope to quicken things. If not, I guess it will just be a time for the two of us to enjoy before the arrival of the baby.

Keep us updated if you go into labor... Let's hope you won't have too much longer to wait either! Good luck hun with your upcoming delivery!
