Ok, here is my response, but it's going to include some information on other's comments, so bear with me!
#1- ITA, he has nights and days confused. It's actually a pretty easy fix. During the day, keep things bright and noisy. Make sure he naps good during the day, but don't let him nap longer than 3 hours or so and make sure to have lots of wake and play time in the sun. At night, keep it very dark and very quiet. When you are feeding him, changing him, etc...., try to keep it short and try not to play with him.
#2- Co sleeping is wonderful and does NOT raise the SIDS rate. Far more babies actually die in cribs. BUT you have to be careful about it. Don't put them on a pillow, keep big blankets away from them, use a guard rail so they can't fall off the bed, never drink, never do drugs, never smoke, etc.... Many, many other countries co-sleep, and not because they are "poor" and can't afford a room. Here are some links showing all of the benefits of co-sleeping, how to do it safely, and what the research says about it.:

#3- Please avoid a feeding schedule. That goes along with Babywise and the Ezzos, who wrote a book based on very, very limited research. Formula fed babies are easier to put on a schedule because formula takes much longer to pass through their system as the proteins in the milk are harder for them to break down. Babywise has been linked with failure to thrive, dehydration, etc... Here are some links on demand feeding and the Babywise book...
