Nipple stimulation is the gentle rubbing or rolling of the nipple to encourage the start of contractions. The theory is that oxytocin, a hormone that causes contractions, is released in the body when the breasts are stimulated.
Is it safe?
A review of studies found that contractions after nipple stimulation did not over-stimulate the uterus, which could be dangerous for the baby (Kavanagh et al 2005). There is a lack of research on the safety of this technique in high-risk pregnancy, so currently it is only recommended in normal pregnancies.
Does it work?
The review mentioned above showed a significant benefit from nipple stimulation in women whose cervix had already started to soften, thin and open ready for labour. 37 per cent women who had tried it went into labour within 72 hours as compared to just 6 per cent of those who had not.
How do I try it?
The idea is to simulate the suckling of a baby so you need to massage the whole areola (the dark area around the nipple), not just tweak the nipple. Place your palm over the areola and move in a circular motion, applying a firm but gentle pressure. This may need to be continued for some time. The usual recommendation is to stimulate the breasts for an hour, three times a day, spending 15 minutes continually stimulating one breast and then alternating to the other breast for 15 minutes until the hour is up.
