My cousin's girlfriend has a 4 week old baby and she is on facebook asking advice about how to get him to sleep better. From what she said last week when I saw her it sounded like he is sleeping about the normal amount for a baby his age. She is getting all kinds of advice from people like letting him CIO at night to giving him cereal in his bottle before bed. I know that none of it is good advice, but I don't know her that well so I don't want to be pushy. Does anybody have links to resources that I can point her to that would back up my opinion. I'm specifically thinking of info about how much an infant should sleep and how often you can expect them to wake up at night, why CIO is not a good idea, or why feeding a 4 week cereal may not be good for the baby. I know that I've learned all of this through the years but I can't think of any places to easily access this info online.
