Newborn sleeping

R

My baby is 2 weeks old and can sleep during the whole day but once it comes to 2ish in the morning he wakes up and stays awake till about 8/9am. Would feed him multiple times during the time but he would fight his sleep.

Has anyone any tips on how to get a 2 week olds clocks changed so he can sleep during the night and stay awake those hrs during the day?
