Nipple stimulation is one natural method that may induce labor. Stimulating your nipples triggers the release of oxytocin, the hormone that helps you release your milk during breastfeeding. However, oxytocin is also the same hormone that triggers uterine contractions when you’re giving birth.
For best results, stimulation should mimic that of
a baby suckling at your breast. You might even want to get your partner to help out with this.
