Sorry I will rephrase... a baby is considered full term and is fully developed at 37 weeks. Although the baby more than likely will be born after 37 weeks

Princessmya... I had a S&S when I was 40w5d with DD#2 and went into labour the next morning.
I am not sure about it speeding up labour if you have been having prelabour for weeks... can't see why not I was having bad prelabour contractions with DD#3 and eventually I tried nipple stimulation (40w1d)and it finally got things going.
