Baby not sleeping 😴😴

Dominique • Myles John 3/8/16. Micah Robert 6/29/17 baby girl due 10/8/20
My 2 month old has been going to sleep in between 11-3am sleeping for almost 3 hrs then after waking every 45/1.😑 every night starting at 9pm I get him ready for bed hoping it will start some sort of routine and keep doing it till he falls asleep when ever that is. I know he's still young and it will change. 
Just a thought, could it be my baby smells me and wants to get picked up? Wondering if I move his bed the otherwise of the room would it help? 
Any advice welcome!!!Â
