Night owl baby

Anyone else have a baby who is a night owl? He’s been this way since about one month old. Will not go to be before 10pm. He’s gone to sleep before then a handful of times. I’m a SAHM so I don’t mind the schedule. He will usually go to sleep between 10-11 and wake up between 9-10. I’ve tried to get him to sleep earlier by adjusting his nap schedule and starting bedtime routine. I even tried to wake him up at the same time every day (7am) for about a week and all that did was just make him grumpy and he still didn’t go to sleep any earlier haha.
