some kids will accept no substitute for being right near mom and dad. that is ok! :D do your best to be sensitive to your baby's needs; you obviously are or you wouldnt have written for advice. my son was this way. we coslept/bedshared until he was between 15-17 months old. he still sleeps in his crib in our room. right now, its just easier for us to not have to crawl all the way across the house to get him if he wakes up, which has been rare... so its probably past time to do something else :P
but im telling you, the more you just have patience and consider your daughters need for you right now, the more confident and secure she will be able to move past this phase! :D my son sleeps WONDERFULLY! :D we have NEVER had a problem with him screaming when he went to bed or anything.... he goes to bed, and either just chills in his bed until he falls asleep, or he goes right to sleep! :D
