I've made quite a few baby quilts that are square using width of fabric. These are used during infancy and are great for covering while rocking little ones or for dragging around. The square ones also are a good size for tucking in around the little ones in car seats if the family lives in cold winter climate. Also to be considered is that the traditional crib size might work for use on toddler beds as most cribs now convert for that use. But, let's face it, for practical use, today's parents/kids like the fleece or minkee covers as they are soft, take "abusive" laundering extremely well and stay soft over those early years.
