Nipple stimulation, can encourage contractions, but usually I would say when you are in early labour already, I would suggest it if a client was in early labour or slow labour or if they were under pressure to start labour (maybe very overdue). Another client expressed colostrum to store in case her baby needed topping up (she was diabetic) and did not want to give formula. www.birthingnaturally.net/cn/technique/nipple.html Selina
You will need to do it quite a lot for it to be effective though I'd imagine. I am currently 34 weeks pregnant and DS is breastfeeding so it will be interesting to see what effect, if any, it has if he decides to have a snack when I'm due or in early labour. It doesn't seem to have any effect on me now, such as an increase in braxton hicks or any twinges which makes me think that you need to do a lot of it to get any effect at all.
