well, its a good thing you dont use cry it out... it only works on the surface, underneath, you teach her that her needs arent important enough to respond to, and that trust breaks down between you. ....
www.askdrsears.com has MANY loving, responsive ways to deal with sleep. william sears has a whole BOOK on sleep and sleep issues, and how to get sleep, all in a loving, responsive, connection-promoting way. so many resources these days promote DISconnection, and thats hurtful to relationships with our children...
anyway
things that i recommend; night light (you probably have this already), make sure temps are good, check the back of her neck if shes too hot the back of her neck will be sweaty.. somehow undress her or lighter blanket or something, a white noise machine OR cd - such as 'for crying out loud' a cd with 8 tracks of different types of white noises.
cosleeping (having her sleep in the same room as you) and bedsharing (where she sleeps in the same bed as you) are both options and they are MUCH safer than people think. rates of SIDS are HIGH in this country, where in places that they cosleep/bedshare as a rule the SIDS rates are DRASTICALLY low. obviously, do it safely, and never when under the influence of any drug, drink, and reduce heavy bedding if bedsharing, otherwise cosleeping is safe no matter what because shes in the same room, you can respond to her faster and she doesnt get too worked up before you hear/get to her.
with babies, sleep is typically never a constant. there is always something that pops up once you think you have it all covered. developmental stages will cause sleep disterbances: rolling over, crawling, standing up, walking, all those things will interrupt sleep.
also, of course, teething.
if you suspect some teething, give her some tylenol and see if that helps her get a longer stretch in. night feedings are still MORE than ok, babies need to eat a LOT and even at night. but never leave baby with a bottle in her mouth, it rots teeth. however, breastfeeding at night, and baby sleeping with the breast in her mouth doesnt cause those same problems, so if you are breastfeeding, its more than ok to fall asleep with her still at the breast. i did that a lot with my son. it really helped ups both sleep.
if you bring her in the same room with you, you will find that you should be waking up at the same time or seconds/minutes before she does. thats an important instinct! :D it helps you not have to totally wake up and you can help her and get right back to sleep.
anyway,
no matter what you are doing, the MOST IMPORTANT PIECE OF INFORMATION FOR PARENTING is to do what you know is best for you and your family. this may change day to day, from being sick to being healthy.... from being at home or being away... its all going to be different day to day. if bedsharing helps her after being away from you at child care, then that is ok! if you cant do it, cosleeping in the same room is also great!
babies cry. but the more you respond to their needs the less they will cry. seriously. the more connected you are, you will figure out sometime around a year that her cries change from a "help me now" cry to a "i need something but its not urgent" sort of cry. its amazing. but never ignore a baby under a year crying, not only will you not notice that time her cries change, but it hardens your heart to where you cant stand her cries in an angry way, instead of in a way that you want to help her, be empathetic to her, and help her get her needs met.
after all, empathy is not something that can be adequatly taught. empathy is learned by experience. if babies are shown it, they will show it to others.
:D anyway, like i said, do wahts best for you and your family. no matter the advice, even my advice, your doctor's advice, your parents and inlaws.... your instincts are the ones that are most important.
good luck!
