After carving a niche in the infant and toddler category with a range of organic wool and cotton bedding, Woolly Boo is adding all linen sleep sacks ($40, wholesale) for Spring ’12. “Linen acts essentially like wool, in terms of moisture absorption and distribution into the atmosphere,” explains founder Selma Avdicevic. Each sack is customizable and is lined with colorful cotton. Avdicevic is especially excited about a graphic black and white airplane design. “I’ve found that parents like untraditional colors, so I’m reigning in my knack for pink, ” she laughs.
