I'm sorry! When my son was a baby, he was like yours. Is there is special toy you can get him attached to during the day, and then take it away at night? That way, he will cry for a few minuites. Then come in with the toy and say "mommy will give you the toy if you lay down!" so he'll lay down and you'll slowly hand him the toy. Try that and see if he falls asleep.
Also, try feeding him milk or cashews before bed. That calms the stomach and helps one sleep better
