Please help me

My baby woke up at 1 am, 230am to poop, and 4am to poop last night. He still awake after 4 am as i'm typing - 8 am now that's 4 hours. He usually sleeps between 5pm till 5 am (11pm milk and straight to sleep. 2 or 3 am poop, stay up for 1 hour and straight to sleep). He usually will start his day wake up at between 7-8am. Please help me. I don't know what's wrong with my baby. Feed him well, diaper clean and change every 3 hours, massage his stomach
