Otterly obsessed. Completely smitten. Absolutely done for.

The Otterly Exhausted Infant Onesie is dressed in a playful coastal print — little otters floating amongst starfish, jellyfish, and swaying seaweed on the softest sage green you've ever seen. It's the kind of onesie that makes strangers stop you at the grocery store. You've been warned.

Built for the beautiful chaos of early days, this onesie features a zipper cover at the neckline, ribbed cuffs and collar for a snug and cosy fit, and a dual-zip design that opens from both top and bottom — because nobody has time to wrestle a onesie at 3am. We see you.

Made from 100% GOTS certified organic cotton. Gentle on new skin, kind to the planet, and designed in Vancouver, BC — with a whole lot of love from our family to yours.

Made with Heart

Every print starts with a spark — a sketch inspired by the woods, the laughter echoing through the cabin, the smell of pine and pancakes. We don’t chase trends; we design stories you can wear. Each pattern is created in-house by our family, for real families.

Life’s messy — laundry shouldn’t be. Machine wash cold with like colors, skip the harsh bleach, and tumble dry low. Remove while warm for that just-right softness, and iron if needed.
