Frequently asked questions

What is TENCEL™ Modal, and why is it better than cotton or bamboo?
TENCEL™ Modal is a plant-based fabric that is exceptionally soft, breathable, and durable. In our testing it stayed softer after washing and held up better than both cotton and bamboo — so pajamas last through hand-me-downs.
Are Tiny Knot pajamas snug-fit and safe for sleep?
Our two-piece pajamas are cut to meet CPSC snug-fit sleepwear guidelines, and every piece is tagless to keep sensitive skin comfortable all night.
How do I choose the right size?
Use the size filter to shop by age, from Newborn through 5T. If your little one is between sizes, we recommend sizing up — the stretchy cuffs grow with them.
How do I care for TENCEL™ Modal pajamas?
Machine wash cold on gentle and tumble dry low. The fabric is designed to get even softer with every wash and resists pilling.
How fast do orders ship, and what if I need a different size?
We offer free U.S. shipping on orders over $49, and most orders ship within a couple of business days. If the fit isn’t quite right, just reach out — we’re happy to help you exchange for a different size.
