Do you change your baby's regular clothes into more comfortable clothes/pjs for his naps? LO is 5 months old and spends most of his time in cotton tops and bottoms OR one pieces. I would love to dress him in cuter clothes (like jeans and sweaters) but he takes 3-4 naps a day and I'm not sure if he would be comfortable sleeping in those clothes.

I should mention that he also gets zipped into a sleep sack.

What do you do?
