Dressing baby at night

Sarah
Hi mamas! I'm wondering about the proper way to dress a newborn at night when we keep our house at about 60. (We're in AK and it will be winter.. so it's expensive to heat!) 
On Pinterest I saw for that temp baby should wear a onesie, covered with a footie sleeper, covered by a fleece swaddle.. or something similar. That sounds too warm to me and like it will be a LOT to take off for diaper changes. What do you think?
