If teaching your baby to find and insert her own paci from the extras in the crib doesn't work, there are a couple of other things you might check into to see if there is another underlying cause for the difficulty sleeping.
Cranio Sacral Massage Therapy: It's ultra-gentle, usually done in an OT/PT clinic by a licensed massage therapist. My oldest didn't sleep all night until 4 years old, so I understand how debilitating your exhaustion is. This type of massage improved my daughter's sleeping DRAMATICALLY. It's not fabulous for everyone, but you'll know after one massage if it's going to be great for your child or not. We use Ken Piercy (www.kenpiercy.com) now, and have used Suzanne at Integrative Pediatric Therapy (www.integrativepediatric.com) in the past. Both are excellent.
Chiropractic Care: Sounds crazy to some, but all 3 of my kids now see a chiropractor. We're all healthier this year than ever before thanks to these adjustments. Look for someone who sees a lot of kids, and ask other moms you know for recommendations. If you get a bad feeling, don't let the person touch your baby. If you trust her/him, this could be really helpful. We see Dr. Melissa Shelton (www.drmelissashelton.com). She sees lots of tiny babies. My youngest started seeing her at 20 monhts, and he loves it. At first it looked just like she was holding him against her chest. The pressure she uses is very gentle. My son actually giggles through his adjustments, and hops up onto the table by himself.
Both of these ideas meet my personal standard of: if it can't hurt, but might help, it's worth a try.
Trust your gut, because you know your child best. Books are great, but remember to filter what you read through your own experience with your child. The author's child might have had a very different temperament than yours, so that solution might not be perfect for your family. You need to sleep, and so does your daughter, so don't give up looking for things you can do to help her. The first thing you try might not work, but keep looking.
Good luck!
