For daytime naps, do you swaddle and put baby in dark room?

At the minute all day time naps are in a bright room either in moses basket, pod or bouncer with a blanket. He sleeps in a sleepbag in the dark at night time - seems to have helped with him knowing the difference between night and day as he has been doing great stretches at night Have you even tried just swaddling for the daytime naps? x
