Hi there, a few questions if you don't mind?
Could you post your daytime routine for us? Does your LO have any medical issues e.g. Reflux? What's your routine at bedtime and does he go to sleep independently (as in go down fully awake and settle himself with no help from you?) does he use a paci? What do you do when he wakes at night?
Hopefully we can help you once we have a bit more info
