Why do we love bamboo?

Gentle on Sensitive Skin

Buttery-soft and hypoallergenic, our bamboo fabric is gentle on sensitive, eczema-prone skin. Cozy comfort for your little birdie, from the first morning snuggle to bedtime.
Cool + Breathable

Breathable bamboo fabric keeps little ones comfy and up to 3° cooler than cotton. Just right for busy days and sweet dreams, all year round.
Grows With Them

Our signature stretch and durable fabric mean up to 3x longer wear. More room to grow and more time in their favorites, through repeat outfits and wash days.
More Sustainable

Bamboo requires less water to grow than cotton, and our durable pieces are made to be loved again and passed along. A little Birdie Bean goodness for the next little birdie.

Fishy Favorite!

Soft, cute shirt perfect for lake days!

The cutest softest pjs

Love these for 2 of our grandbabies!

The most fun checkered set!

We absolutely love how bright and fun these pjs are for our boys. They’re so soft and will last us a long time!

Preemie

We adore the quality of this brand & the adorable prints. What made it even more special to us was it came in preemie size. We weren’t expecting a tiny baby. We ordered these and got them quickly. Hattie was 5lbs, preemie was still big on her but they worked. She will get several Months out of them due to the yummy softness & stretch! We are Birdie Bean lifers! 🩷
