Suddenly not sleeping at night

My son was giving me from 10:30-4:30 every night. Now all of a sudden he's sleeps maybe an hour if that and toss and turns and fusses all night. I think it's gas because he's pulling his knees up and eventually he'll poop. I'll change him and he'll still not fall asleep. Anyone going through the same thing??
