Another oxytocin booster involves, well, playing with your nipples. You can look up how to do this "properly" to induce labor, but I kinda just winged it while watching TV or standing in the shower. I felt pretty silly, and it got uncomfortable since my breasts were sore in late pregnancy. But I figured if squeezing and fondling my boobs would lead to my baby's birth, then what the heck?
The verdict: I was still pregnant after stimulating my nipples and more than just a little over touching myself for no reason.
