My 8 month old doesn't sleep longer than 4-5 hours at a time! Unfortunately the Cry it Out Method did not work like it did with my 20 month old. I don't know what to do!
The three key things to help a baby sleep through the night is (1) set sleep schedule that includes an early bedtime, (2) a consistent bedtime routine, and (3) falling asleep independently at bedtime. If your little one needs your help to fall asleep, then start with just making changes at bedtime, taking small steps until he is able to fall asleep on his own. For example, if your little nurses to sleep, then a first step is to move his feeding to the beginning of his bedtime routine but still rock him to sleep. Once he can fall asleep easily without needing to feed, then put him in his crib to fall asleep but stay and pat him. A few days later, sit halfway across his room. Slow and consistent changes will usually do the trick. If he, however, seems to be in pain during the night, be sure and talk to your health care provider.
