Hang in there ladies!
Hey, how do you "try" to keep them going?
I kinda figured they did their own thing. With DD they just came on and kept on...never considered having to "keep" them going?
walking, nipple stimulation, sex/orgasm, things that keep you from letting the muscles relax too much, cat/cow yoga positions
for instance I wouldn't take a nice calming bath or go to sleep immediately
though usually if you can't keep them going, then they weren't meant to keep going... but usually these types of contractions are good for maneuvering your LO into a better position if necessary
