While you are in your favorite department store searching for the perfect cute nighties of for your baby, there are probably dozens of fabrics that you come across among the search. Of course, you want to give your little one the best pajamas you can find, no matter the cost, but just what is the best, exactly? How are you supposed to know what will suit your precious baby best just by feeling textiles, seeing colors, and reading the smeared black print on tiny clothing labels?

Don’t fret, mama bear. In a world full of variety, when it comes to pajamas, there is only one fabric that will give your baby’s nightie both comfort and the cuteness factor: cotton.

Your newborn can sleep anywhere between 10.5 and 18 hours a day; with that much time for dreaming, wouldn’t you want to be comfortable, too? Here are three health benefits that those cute pajamas made of cotton will give your baby–and a fun fashion one, too.

Cotton breathes so that your baby can, too. 

Cotton is a material that is naturally lightweight and breathable, which promotes better air circulation, unlike other heavier or man-made fibers. Due to cotton’s breathable nature, your baby’s body will not labor too hard for climate control, which means less sweating or shivering. Even in the winter months when your little one needs a little extra material to cozy up to, cotton flannel style pajamas are available.

Double threat: cotton is hypoallergenic AND can be organic. 

Does your bundle of joy have sensitive skin? Do you want to be sure that they are getting soft, natural material that is not treated with any chemicals during processing? Cotton can give you both, so that you know you are dressing your baby in clean, pure pajamas.

You will sleep like a baby–and so will your baby. 

Cotton is one of the softest and most nonabrasive materials you can choose for your little one’s pajamas. It has been used for thousands of years for a reason: the material is naturally smooth and soothing to an infant’s skin. Ultra-soft materials like silk and satin and manufactured materials like nylon and polyester can trigger skin allergies and are poor conductors of excess body heat, so your baby could begin sweating profusely in the nighttime. The less irritated your child is by his pajamas, the less he will wake up in a fuss, saving you some much needed shuteye, too.

Are the pajamas not enough? Cotton is a durable, easy to clean fabric that can be used all over your home; from hand towels to pillowcases, there are few linens that cannot be replaced by cotton. If you do not trust the practices of people who have loved cotton for thousands of years, just try it for yourself and watch the benefits spring up all around you.
