“Hello World!” (from the classic computer program) seems especially appropriate on onesies and tiny t-shirts to introduce your newborn to the world. I chose the font “Intro” not only for its extreme cuteness, but also for the little inside graphic design joke of the typeface name. Makes a great shower gift. Get a Onesie and a Toddler T-shirt because you know they grow so fast! Available in white and old-school computer monitor RGB green (aka “Lime Green”). Onesies sizes: Newborn, 6 months, 12 months, 18 months, and 24 months. T-shirt sizes: Extra Small, Small, Medium, Large, and Extra Large.
