Your swaddling technique? Passable. Good thing Nipper’s finally outgrown the nightly wrestling match. Time to bundle him into the crème de la crème of Euro slumberwear: a quilted infant or toddler sleep sack from IE Boutique. Imported by Hayes Valley’s Lotus Bleu, these stunners come in quirky, lushly hued prints (bowling pins, dahlias) inspired by the artisan traditions of Japan and Nepal. Quilted for softness and warmth, they’re just the thing for San Francisco’s frigid summers. And they close easily: With a quick zip and a couple of ties, baby will be ready for beddie. And you’ll all get a good night’s sleep. Available at Lotus Bleu, 327 Hayes Street, between Gough and Franklin Streets (415-861-2700 or lotusbleu.com).
