How to get 2 month old on sleep schedule

My baby is 2 months and every night he sleeps 2:30am or 3am for four hours, then wakes up and eats and goes back to sleep for another hour. By that time, it's 12 or 1 in the afternoon! I hate going to sleep so late. He kind of put himself on this schedule by I want to get him to bed at least by 11pm! But I have no idea how to do it. I know they say to keep him up during the day but I don't want to deprive him of his sleep if he's tired.
