BuzziBreeze Baby and Tai fit up to 2 years. BuzziBreeze Plus from 18 months up to 6 years.
The basic rule is:
Baby carriers fit as long as your child's knees are higher in the carrier than his or her bottom.
We always recommend: buy a baby carrier so that it fits NOW and not to grow into. The most important thing is the ideal fit for small babies. Baby carriers are not made to grow into, but to grow out of. Missing a few cm/in to the back of the knee later is no problem!
