Sleep help PLEEEEASE

My little boys sleep is literally all over the place. No matter how hard I try.

Last night he was up 3 times - up for the day at 530 and slept for 5 minutes in the day. He's finally fell asleep at 7 but I can tell he's going to be constantly up and down all night.

He barley naps and his night time sleep is terrible 🙈 Im barely sleeping and constantly at work like a zombie. Please help
