Shh/pat didn't work here either. I decided to stop spending hour after hour day after day on it and get back to my life (and Josie's too, as I was neglecting her trying to get Nat to sleep!
).
I broke down and used the Baby Bjorn or sling if nothing else worked, or just held her to sleep while J and I read books or played quietly together. I also shamelessly took the kids on errands so Nat would nap in the car and I could put her in bed when we got home. Time passed and while Nat still (at 3YO) wants us with her to fall asleep at night, the rest of the time she's become quite an independent child (who this past weekend painted her own fingernails and toenails AND cleaned up herself!
), so in the long run I'd say it's worth it for us. Each family needs to make its own decision, but I found that by working with my kid and who she was/is, it saved me broken hopes and dreams of putting down an "Angle baby that I just didn't have!
(And I mean that with love and admiration for who she is, BTW.
I did get good at working out when she was asleep enough to take out of a carrier and put in bed for times when I needed my body free (shower, laundry, mowing lawn, sanity, that kind of thing).
