Birthday presents, paychecks, babies. You don’t mind when things come early, but to get that bundle of joy who arrives a tad on the unexpected side? A pint-size ensemble from Sage Baby’s preemie line, of course. The tiny collection covers all the basics, from classic-striped layettes to organic cotton kimonos with side snaps for easy diaper changes. Even the skull hats are geared for babies who max out in the two-to-six-pound range. Each piece is simple and easy to care for. And what they lack in size, they more than make up for in style. And that’s big news. Available online at sagebabynyc.com.
