Onbuhimo Sizing

Explore the world
while keeping your little ones close.

2Lambie offers three onbuhimo sizes, including one of the only carriers on the market specifically designed for preschoolers! Baby size is perfect for those who want to buy once, keep through early toddlerhood. Toddler size is the best choice for your little one that is approaching 2 years old through 3T+. Preschool size is wonderful for older children with special needs who often need those quick "ups".

  • Baby: From 8 lbs with cinched panel - 18 month clothing size, 14-16" seat, pant size: sitting - 18month/2T
  • Toddler: From 18 month clothing size with cinched panel - 4+ yrs, 25-45 lbs, starting at 32" tall, 16-18.5" seat, pant size: 2T/3T - 4T

Our shoulder straps come in one-size fits most, the perfect fit for nearly all body types is a simple adjustment away. Straps are 15" total padding length and 4" padding width that tapers toward buckle. Straps will fit more like 12" when comparing to other onbuhimo brands, due to the 2Lambie curved backrest panel shape and our inset buckles.
