FAQ
Why do regular diapers roll on chunky babies?
Most diapers use a fixed-elastic waistband that compresses round bellies. Bamboo waistbands flex with the body. See Cuddle Kin sizing.
Should I size up or use a different brand?
Try a flex-waist bamboo brand first; sizing up creates leg-gap leaks.
Is OEKO-TEX 100 Class I important?
Yes — Class I certifies for skin-contact safety on babies under 3 years.
Do bamboo diapers fit chunky thighs too?
Yes — bamboo wings stretch instead of pinch.
