Little Astronaut Adult Onesie – Blast Off Into Little Space!
$59.00 USD
Daddy’s/Mommy’s tiniest astronaut has landed! This dreamy all-over print is packed with the cutest space-regression icons: padded baby astronauts floating with their teddy bears, diapered rocket ships, pacifier satellites, glowing pastel planets, smiling crescent moons wearing nightcaps, sparkly stars, fluffy nebula clouds, and milk-filled baby bottles drifting through the cosmos. Everything is rendered in the softest watercolor pastels on a creamy galaxy background — pure little-space magic.
Perfect for bedtime missions, daytime regression, or just feeling extra small and floaty while thickly padded.
Why every little and caregiver is obsessed:
- 100% ultra-soft cotton (180g/m²) – gentle on sensitive skin, breathable for all-day (or all-night) wear
- Snap crotch for hassle-free diaper checks and changes, no matter how deep in little space you are
- Short-sleeve bodysuit fit – works as jammies, a discreet bottoming layer, or standalone cuteness
- Space + ABDL combo that’s still rare – you won’t see this everywhere!
- Seamless repeating print – adorable from every angle
