Getting baby back to sleep at night?

My baby is a terrible night sleeper but as he’s getting older (6 weeks) he’s awake a lot more after feedings. He’s usually happy but cries if put down so he seems to want to be kept busy. This is totally fine in the day time, we read, look at things, etc. but he does this at night after he’s been fed, he’s awake for over an hour and i can’t get him to go back to sleep. I keep it dark and quiet and swaddle him. Any other tips? Or is that just the norm? I know he’s young so we’re just on his schedule but I’m trying to figure out how to teach him nights and days or is that something that corrects itself over time?

FTM obviously 😅
