ive answered this question more times than i can count.
i would HIGHLY recommend www.askdrsears.com, use EXTREME CAUTION when considering any type of crying with your baby. crying is their only form of urgent communication, you need to listen to it, trust your intuition. do what your heart urges you to do.
also, join a moms group of some kind, like hte la leche league. its more than just breastfeeding, though it is based on that obviously. find some sort of moms group in your area that can support you and give you help.
however, i highly recommend dr sears's information. at the least, he gives you permission to follow your instincts no matter how many people tell you that you are doing it 'wrong'.
you dont need to get her in her own bed in order for her to sleep on her own. basically, she wont be able to learn how to sleep on her own, and sleep is something thats nurtured not taught. the more you can give her comfort and the feeling of safety when shes going to bed, the easier it will be for her to mature into sleeping on her own. its really something she matures into, not learns.
cosleeping is safe, it is not going to cause any bad habits, and it will teach your baby that sleep is a happy thing, a relaxing thing, a comforting thing. my son coslept with us most nights until between 15-17 months old, when he started sleeping in his own bed in our room. he is 2 and he still sleeps in his crib in our room. basically, he is right there, if something happens and he wakes up, we are right there and he doesnt have to get too worked up before we get to him.
things we make sure we use when its bedtime is routine, prayer, that kind of thing, night light, white noise, and we leave him in bed, not alone, but with a bear, a couple books, that kind of thing. that way they fall asleep during a relaxing activity instead of thinking they are all alone and being nervous.
consider teething issues, perhaps give some tylenol.
but TRUST me on this one, she wont want to sleep in your bed forever, she WILL sleep in her own bed and its actually very healthy to her sleep habits to cosleep for a while. you can always wrap her in a blanket when you lay with her and try moving her after shes DEEP asleep. you have to make sure that shes really really asleep.
just trust yourself. you are the only person who has the instincts for your child. you know what she needs, trust it, and dont listen to anyone who tells you not to do the things that your daughter needs.
