Some of the hospitals offer classes...I took one at Swedish when my older son was born. I remember they didn't want babies with older siblings in that class (germs, presumably), though, so be sure to check on that.
Another resource you might like is ItsyBitsy Yoga. There are only a few places that teach it in Denver...you can find a list at www.itsybitsyyoga.com. There's also a book and I've seen videos at the Jeffco libraries. My son LOVED baby yoga and this one is different 'cause it's not baby-mom yoga; this one is JUST about the babies. It teaches some great ways to calm baby when they're upset (which I'd think would help her learn to self-soothe.
It may be a bit early for sleep training but the book 'Good Night, Sleep /tight' by Kim West & Joanne Kenen is also really good. (www.sleeplady.com) There may be some good, tear-free soothing suggestions in there.
A bounce on the yoga ball has always been a huge calmer in our house. Not sure I'd have made it w/o one of those!
Best of luck with the new babe! Hope your journey to getting her settled goes smoothly from here on out!
