Quoting Thebestmommyever Miles:" Give me some ideas..."
Jump off the Empire State Building. But that's only if you live close enough to New York to have a quick trip, and if you're an adrenaline junkie like me
Call me and I'll try to catch you when you reach the ground. I'm sure it would get something starting in your uterus!!!
But if you don't prefer that...
I heard that driving over a bumpy road could work.
Sex, is another thing that tends to work well from what I've heard.
Someone I knew tried walking up and down the stairs in her house, so I'm assuming that kind of physical activity may do the trick.
But I'd also advise you to wait until your baby's ready, to ensure his safety and health at all costs!
