Crib sheets must be 3 things - comfortable, durable and cute. You also should have a few on hand in case you have to do a middle of the night change. Here are my favorites:
--> Burt's Bees crib sheets are 100% organic cotton, come in over 20 patterns and have a snug fit. You can't go wrong with these.

--> aden + anais is another favorite baby brand. Known for their 100% cotton muslin, they are soft and breathable.

--> Copper Pearl are a more premium option. Such adorable trendy prints and the softest knit rayon fabric you have felt.
