it is unreasonable to expect your baby to sleep through the night. "through the night" at a 2 month old's age is no more than 4 or 5 hours at night. their stomachs are just too small to sleep longer than that. and DONT let anyone tell you feeding her cereal will help, it wont. it actually will wake baby up more because digesting keeps them awake, and can also give them reflux, or heartburn...
i highly recommend checking out this website:

the sears family has the GREATEST information on just about everything, and they are trustworthy since they had 8 children of their own..! i hope that helps. my son is 16 months old and he doesnt always sleep through the night.
your relatiionship with your baby will be a whole lot more fulfilling if you dont expect too much from baby. my husband expected our son to sleep through the night at 3 months and when he didnt he became pretty dissappointed. so remember not to expect too much.
to help those sleeping hours extend to 4 or 5 hours more reliable, having a white noise cd or sound playing. that still helps my son!
i whole heartedly agree with what shawna s has to say. dont feel like you have to resort to crying it out. the most horrible thing in the world is knowing your baby and that baby needs you, and having someone tell you that you cant hold baby when they are crying. i IGNORED this type of advice because those people are not emotionally connected to my baby and they DO NOT know what my baby needs. i responded to my son every time he cried, and depending on what he needed, i made sure he got it. babies dont understand the difference between needs and wants until they are almost a year old. i notice a difference in the way my son cried when he started figuring out need vs want. if you dont respond to them when they are younger, they start learning that no one listens to them and their communication isnt beneficial, and they stop communicating. make sense?
anyway, check out william sears's information. they have TONS of books that are fantastic. but again, dont expect too much of your children, and they will surprise you instead of dissappointing you.
