You'll do it LGT! Pelvises can stretch! That's what the bit in the middle is for... . And a midwife's finger can sort out the shoulder stuff. Get reading some Ina May Gaskin - that should do the trick. Seriously, though I hope you're OK. Thinking of you!
Ooogs - I've got the MBF book on twins and sleeping if you'd like it? My email is [email protected]. Mail me your address. I start at 5ish and do: supper, then bath, then feed quietly with a story, then burps and cuddles, tuck into sleeping bag, dummies in, taggy blankets wrapped around their heads (they go over heads in winter and in the pram! ), kisses, night-nights, blackout blind up and curtains drawn, lights (if any) out, leave the room and close the door. Firmly.
I was going back a few times in the evening to replug dummies, reburp, recuddle, etc, all in the dark for a fair while, but at 6 months now I don't need to unless they've got a sticky burp which wouldn't move as they went to bed. All of the above takes til about 7.30, but also involves doing DD too. I always do the same routine every night so they know what's coming and what it means. Consistency and dark are the keys! If you can't see you get bored and then you might as well sleep as not... iyswim!
