Nights and days switched

My 7 week old has his nights and days switched. I was reading on how to switch them back. It was saying to try and keep them up more during the day, and other things. They say this also works for newborns, but it's hard to keep a newborn awake and I feel like he needs his sleep right now no matter what time it is. Would y'all recommend that I just give him a couple more months before I really try it? When he doesn't need as much sleep and when it's easier to keep him up? (I'm a stay at home mom)
