4mo advice

Hi! My 16 week old (4months next week) goes down around 7… wakes at like 1130, 1230 ( we replace paci and he goes back) then persistently at 1:30 and won’t go back down til fed… it’s same routine every night which makes me question if he’s actually hungry. How can I help this. Should I try pushing back bedtime? Going cold turkey with paci? Help!!
