Newborn nap problems

My 4 week old hits his 14-18 hours per day of sleep but he is awake sometimes for 3-4 hours at a time. He is happy and content, he doesn’t cry, he eats a couple times then naps for a couple hours. But my doctor said any amount of wake time over an hour is bad. I cannot make him sleep. I have a white noise machine, I swaddle, I don’t swaddle, I have lights on, lights off, I tried baby massage, I’ve tried everything. He just wants to be awake.

I am losing my mind. I am spending my WHOLE DAY trying to get him to sleep to the point where I don’t leave my room. I am so worried I’m stunting his development by not being able to get him to sleep faster.
