Cleared for takeoff! This sage green baby onesie® features a charming vintage biplane soaring above the hand-lettered phrase "Daddy's Little Co-Pilot" — the kind of retro illustration that looks like it was pulled straight from a 1940s travel poster. The soft, muted green tone and classic aviation styling give it a timeless, nursery-ready feel that's sweet without being saccharine.
Whether headed for tummy time or a Sunday flight around the living room, this little aviator-in-training will be ready for duty alongside their favorite grown-up co-pilot.
Makes a great gift for:
- The new dad who dreams of matching flight jackets someday
- A baby shower gift for aviation-loving parents-to-be
- Father's Day, from the smallest crew member on board

Our ONESIES® are made from 100% cotton interlock knit, in white, natural, and heather grey. The natural fabric fits true to size, while the white tends to run slightly small. Our shirts and sweatshirts are crafted from cotton or cotton blends, depending on the brand. When in doubt, sizing up is a safe bet.
All of our items are printed using inks that meet CPSIA safety standards and are gentle on sensitive skin.
