Fit for Very Small Babies
Little Sleepies preemie Zippies are designed with a snug fit, but a true micro preemie may need a smaller fit than preemie sizing offers. If you are shopping for a very small baby, check the size details carefully to find the best fit.
Zippies can still be a thoughtful option when you want softness and practical features in one piece. They are made from custom-milled Lunaluxe® Bamboo, which feels buttery soft and is gentle on sensitive or eczema-prone skin. That gives parents the comfort they are looking for, along with practical details that make early routines a little easier.
Fold-over mittens help protect tiny cheeks, while the zipper cover and no interior tags add comfort against delicate skin. The double zipper also helps make changes simpler, especially in those early days when everyone is a little tired and doing their best.
Why Parents Love Zippies
Made from custom-milled Lunaluxe® Bamboo, Zippies are soft, stretchy, and gentle on delicate skin. Seasonless fabric helps keep baby cool in the summer and cozy in the winter, so it works well through naps, cuddles, and all the in-between moments.
The comfort continues in the little details. Fold-over sleeve cuff mittens help protect tiny cheeks from scratches, while fold-over leg cuffs convert from a footless romper to a footed sleeper as baby grows. A double zipper makes diaper changes easier, especially overnight.
Thoughtful Comfort Details
Zippies are made without snaps, buttons, or interior tags, which means less fuss and fewer scratchy distractions. A zipper cover adds comfort near the neckline, and the snug fit follows CPSC safety regulations. They are never treated with flame-retardants or chemicals.
They also fit up-to-3x longer than the average sleeper, making them a practical favorite for longer wear.
How to Decide if Zippies Are the Right Next Step
If you are shopping for a baby who is especially tiny, start with fit first. Zippies are designed with a snug fit, but some families may prefer to wait until baby is ready for a little more room before moving into Zippies.
It also helps to think about how you will use them day to day. For bonding time, stroller rides, naps, and all those in-between moments, a soft zip-up one-piece can be a helpful option. The double zipper makes diaper changes simpler, while the convertible foot cuffs give you flexibility as baby grows.
What to Look For
- Skin comfort: Lunaluxe® Bamboo is gentle on sensitive or eczema-prone skin.
- Easy changes: A double zipper helps make overnight changes less disruptive.
- Flexible wear: Fold-over mittens and foot cuffs add function without extra layers.
- Longer use: Stretch and convertible details help extend wear over time.
If you are buying ahead, Zippies can be a smart choice for a later newborn stage. And if you are gifting, the bamboo keepsake bag is a nice extra that can double as a gift bag.
