Co-sleeping and pacifier cured that for me with my first, even though I only nursed for a very short period. She just wanted to suck & sleep with us...she'd get mad if she was latched on & breastmilk got in her mouth; wasn't hungry, just wanted to suck. I just slept with an arm between her & the pillow, and no covers. Worked quite well. Good luck! Any way you get sleep is a good way!
