A couple of months ago our 18 month old daughter was teething, had a stuffy nose and a cough. We had to sleep with her sitting up to prevent postnasal drip . If we didn't a horrible cough would start and result in gagging and she would end up throwing up. I'm afraid this may have created a bad habbit because now she wakes up every night and winds up in our bed. Once in a blue moon she will sleep the entire night in her crib. Before this she was sleeping a good 10 hours in her crib without waking, or if she did she would put herself back to sleep. She would also sit with Mom for a couple minutes then ask to go night night and off she would go without a fuss. Now I have to rock her until she falls asleep. We have tried letting her cry , which resulted in crying for two hours off and on and getting herself so worked up she was shaking. I don't want her to feel abandoned, but I want her to be able to Drift off to sleep without someone always being there. As soon as her head hits the pillow in our bed she is out like a light most nights.
