With the name, Firefly Diapers, it only made sense that something should glow. In this case, the glowing trim and snaps on the Firefly Sleeptight nighttime diaper are made from a naturally luminescent mineral embedded in polyester and poly-resin.

To help the diaper trim glow brightly, hold it up to a bright light (uncovered light bulb, direct sunlight).

Trim for nighttime. Since the bulk of the absorbency is in the wet zone, even this thick nighttime diaper is quite trim around the hips.
Quick on and off, with snap closures.
Absorbent. With wings folded, diaper has 9 layers of fleece and the doubler has 3 more.
Quick drying. When wings (the soaker pads) unfold, there are no more than three layers in any one part of the diaper.
Environmentally friendly 100% certified organic cotton knit.

Care note:

• If you dry your diapers on the line, put the Sleep Tight diapers in the shade. UV light from the sun can degrade the plastic snaps so they will no longer glow.

You might consider:

• Use a large flat diaper to line the sleeping space for a newborn.
• Try Firefly Easy Wool diaper covers for nighttime. Wool breathes and keeps baby from overheating.
