There could be other reasons he is waking up, like teething or he could be having a growth spurt, which could be leaving him actually hungry at night (they burn lots of energy growing, and need to eat more and more often) or he could be having growing pains. Most likely he just needs to get use to not being swaddled and wiggling. Give him time, be consistant, and try not to pick him up too much, unless he really needs to eat or be changed. Just go into the room, reassure him you are there, cover him up again and pat him on his tummy or whereever. After a while he will learn to just go back to sleep on his own. Good Luck!
