Is it too early to tell?

I think my 17 day old has his days and nights mixed up. Right now it's about 10:00 pm and he's not falling asleep as easily as he does during the day. I open the windows and make sure it's bright; I don't tip toe around him; my older son talks and plays games and watches tv around him ; we try to make it as noisy and busy as possible. Today we spent most of the day out the house!

Any suggestions? We have tried swaddling him, and it only worked for one night. Last night it didn't work at all; he woke up and was sweating. He finally fell asleep when he was laying with me in bed. When I went to put him in his bassinet, he'd wake up and cry.
