The Best Nerdy Baby Onesies: Cute Geeky Baby Clothes

A nerdy baby onesie tells everyone who meets your kid just what sort of parents they have! I also love that most of these nerdy baby onesies are great for boys or girls! I bought some of these outfits so that my little girl’s closet has more than pink outfits, ruffled dresses, and glittery headbands.

“Night gathers, and now my day begins. It shall not end until dawn. I shall take no bottle, hold no pacifier, wet every diaper. I shall wear no swaddle and win no sleep. I shall live and cry at my crib. I am the lullaby in the darkness. I am the wailer on the walls. I am the blanket that snuggles against the cold, the nightlight that brings the dawn, the scream that wakes the sleepers, the shield that guards the slumber of parents. I pledge my life and honor to the Night’s Watch, for this night and all the nights to come.”
