BIMBI is available in two sizes – Mini and Maxi. There is a size chart on the Internet with recommended weight and age, as well as measurements including even the length of the waist belt (a detail, but certainly a wonderful one!). May all the manufacturers of carriers inspire by this! I lack only the recommended height to be absolutely satisfied.
Emilka and I tested the Maxi size. This is recommended for kids from 8 months till 4 years of age / from 9 to 20 kg. Emilka is little – she is 18 months old, something between 75 and 80 cm tall, weighing c. 9,5 kg. The Maxi size fit nicely, although – I could certainly imagine the back panel to be a bit longer in the perspective of assumed growth.
