Well, this is how it "should" be, but in reality, it does not always be that way. Sometimes they are going through "growth spurts" and yes, they eat/drink/nurse more at these periods. Sometimes it's teething or gas, or growing pains...at certain stages of development, their brains and physical growth changes too and they go through lots of adjustments as well. Sleep patterns are not static. It changes. They start to have perhaps "separation anxiety" even when they are supposed to be sleeping and want to know where you are... they are cognizant of a lot more and their understanding of their surroundings and routines are growing too etc. But each baby is different, with different temperaments and different personalities and levels of adjustment abilities. Also, "sleeping through the night" at a certain age is not something that "has" to happen, and it is not something that ALL babies do. The Ferber techniques and Dr. Sears advice is something that helps a lot of parents. But in my case, it did not help with my first child, but with my second child it did. EACH baby is different. It is not always a slam dunk. I know it's hard... but hang in there. Try "crying it out"... but it has to be consistent...but go with your gut, on what is appropriate for your baby. With my first child, crying it out did not work at all, after doing it correctly to a "T"... we just opted with the temperament of OUR child and what comforted her. Also, at 6 months, use age appropriate approaches. I don't have an "answer" per say, but just wanted to relay our experiences to you. I really wish you the best... I know it's tiring. Good luck!
