Weight group, up to
The weight group determines the
maximum weight of a baby that can be carried in a kangaroo/sling. This weight should not be exceeded: although backpacks and slings are usually made with a margin of safety, but the service life when exceeding the weight is significantly reduced, simply put — the carrier can fail at any time. In addition, the maximum design weight is not only related to durability, but also to the design of the backpack/sling, and if it is exceeded, both the mother and heavy baby may be uncomfortable.
Lying position
The possibility of placing a child in a kangaroo/sling in a
lying position. This position is considered optimal for babies, because it creates a minimum load on the spine, while it is just being formed; and for older ones it can come in handy — for example, lying down a kid falls asleep much better.
Lumbar support
Lumbar support is primarily designed to provide comfort to the mother while carrying the child. Thanks to this belt, which tightens at the waist, carrying the child for a longer time will not bother. And all thanks to the best distribution of the load on the back.
Headrest
The presence in the design of the kangaroo/sling of a special
headrest. This headrest ensures the optimal position of the baby's head and protects it from strong displacements that could damage the spine. And some options cover the head not only from the back, but also from the sides, providing additional protection from both accidental contact with surrounding objects and bad weather.
Bib
The presence of a
bib in the delivery set of kangaroo/sling. Unlike the classic use (when the bib is attached to the child's chest and protects his/her clothes from contamination), in this case it is attached at the level of the baby's head and covers the parent's clothes. A very useful feature when carrying the baby facing the mother (see "Orientation").
Back pocket
The presence of a
pocket on the outside; commonly found in kangaroo backpacks. This pocket can be used to transport a variety of additional items, ranging from toys and baby food jars to documents and other personal items.
