Lo sleeping thru the night amen!

So I dont go back to work till sept 18 but I figured I start at 2months to get him to sleep thru night. My body is so used to showering right before bed that literally I am yawning while in the shower I figured I get the baby used to it too. So for the last three nights I've been giving a nice warm bath and feeding him an oz more than his normal feeding and then putting him to bed. He slept last night from 10:30 till 630am. I also have to keep the lights off he sleeps in the room wit me if I keep the light on he will stay up.
