Our son is almost 1 and he does the same thing. When he was about 3 months he would fuss like no other and have to be held with his head on my left shoulder and bounced. Few months later he had to be held with his head on my chest but rocked in our glider and would babble my ear off. Then he had to be cradled and rocked, and then facing outward (his back to my tummy) and rocked and cursed me out in baby talk lol Now we have to play his underwater projector with the lullabys playing. It gives him something to look at on the ceiling and he loves the music. We turn it on, give him kisses and say "We love you! Now it's time to go nite nite", leave the room, let him fuss and 15 minutes after the fussing has stopped we check on him to make sure he's covered up. This happens almost every single night. I have never thought of my son to be high needs, and I still don't think he is. He's a great sleeper and I will do what it takes to help him go to sleep comfortably (that means mommy and daddy get good sleep). It's just how he falls asleep, and the name of the game is adjusting.
Your son is fine, he just has a very active mind which is great! We got our underwater ceiling projector from Wal-Mart (you can choose to play lullabys or underwater/ocean sounds)... small investment with a big reward. I suggest also that you don't stay in the room until he falls asleep. Our son would keep checking to see if we were still there, so that didn't work for us. Give him love, play his lullabys and walk out. Hope this helps... Good Luck!!!
