I'm in the same tired and sometimes frustrating boat with you! My 1-year-old fights sleep like mad. After nursing at naptime it takes 10-20 minutes of holding for him to fall asleep, and at bedtime it takes about an hour. If I put him down before he is asleep (or almost there), he drags his tired body up and crawls around until he falls over from fatigue (which takes even longer than holding him does!).
I'm not sure if this will help in the long term, but lately I've been trying to avoid singing, rocking, coochie-cooing him to sleep. After he pulls off the breast, I just hold him. If he cries out I'll comfort him verbally, but otherwise it's just me or my husband holding him. I see my job as helping him relax his limbs/body, and his job is to fall sleep. I'm longing for the day he can understand my talk about laying down quietly, relaxing our muscles, and closing our eyes.
T I always thought that the phrase "sleep fighting" suggested a rather violent struggle, so I've been surprised at how gently Little P fights sleep. He has the eyes-wide-open-and-unblinking phase, which I love, because in the dim room it looks like his face is all eyes. Then there is phase where he starts to drifts off and then pulls himself together and looks around a bit to make sure nobody noticed. Then there is the dragging-the-eyelids-up phase, interspersed with eyes open, eyes shut, eyes open, eyes shut, eyes open, eyes shut. Eyes open. Eyes shut. Eyes open. Eyes shut. Eyes open.
Darn it, open again.
