Some of us do! 
Bother. Baby hasn’t descended enough to do a stretch and sweep, so I’m back to lots of sex, raspberry leaf tea, and jumping up and down. Oh, and maybe having snowstorms and my other kid get sick. That might work too.
Dammit. I was hoping for a different update from you! Sorry…
I’m impressed at you giving lots of sex a go - I can’t imagine anything worse at this point, personally. Don’t tell my husband I said that, though
I’ve been taking a lot of notes from this thread. I’m happy for my wee chap to stay put for the next week, but after that point, all bets are off. I may even try the sex thing!
My mom swore by long walks for inducing labor, and I do mean long. She might be on to something; all three of mine came along the day after I walked 4 miles (Whatsit Jr.), 3 miles (MiniWhatsit), and 2 miles (Whatsit the Youngest). There is probably some commentary to be made there about relative fitness and motivation levels with subsequent children, but I will leave that as an exercise for the reader. 
Unfortunately I’m not allowed to take long walks right now. It’s a pity, because I love walking.
I don’t suggest you try what my mom did with her first kid - doing a little roofing in August in Saskatchewan. Although if you get desperate enough…
