Baby Has Rug Burn From Crawling

When my kids were little and crawling a lot whenever i knew they would be playing in the floor and crawling quite a bit i tried to keep them in pants rather than shorts in order to keep them from getting rug burn and to keep them cleaner especially if i was at someone elses house and they were crawling on their floors.
