Baby doesn't sleep well during the day

So my baby sleeps pretty well in his crib during the night. During the day when it is time for a nap, is the opposite. I nurse him because he can't fall asleep on his own. The problem is that he is such a light sleeper during the day that once i feel like he is asleep enough to put him down, he wakes right back up?! Even when i swaddle him..

Is there any way that i can potentially fix this? He just will not get good rest during the day and will end up be extremely fussy.
