No Cry Sleep Solution by Elizabeth Pantly
My daughter also co-slept until 21 months. She had a growth spurt and major change of eating habits at 18 months and then a couple colds so this winter was a bit hectic. We wanted her sleeping in her own bed before our second arrives this summer. We kept my daughter co-sleeping until she was no longer regularly waking to nurse. She was sick last week so she did nurse overnight and co-sleep, but now that she feels better, she's back to her own bed. When she would wake and want to comfort nurse, I would simply tell her "milk is all gone now. You already ate it. Let's snuggle and there will be milk in the morning" There were lots of variations on that, but the message was always the same that there wasn't milk right then, but that there would be later. She didn't always like that answer, but I never let her cry it out. If she insisted on milk, then she nursed. The more I stuck with my story, the more okay she was to snuggle without nursing. I waited until she was consistently sleeping through the night before we moved her to her own bed. We're all sleeping better now since she's not kicking me in the face anymore! :) Let me know if I can be any more help!
