My LO is almost 17 months old and we still bf at naps/bedtime. Lately I've been having trouble getting her to unlatch. She sleeps in her own crib and I usually rock her/nurse her about 10 minutes and then she falls asleep in her crib. However, now she's been refusing to unlatch and she's holding me there hostage. When I tell her it's time for night night, she shakes her head no (with my nipple still in her mouth) and refuses to release me. She's got teeth too so I can't just pull it out of her mouth. Eventually she'll let me go but I'd like to be the one that tells her when it's time for sleep and not the other way around. Any suggestions?
