[0] Baby Hip Carriers [1] Good (Hip/waist support but single shoulder only) [2] 16kgs or up to 2 years old* [4] Hip carrying is not the most ergonomic position but it is a better alternative to forward facing positions that some carriers offer that require baby to be hung by their crotch which is not good for the baby's spinal development. [3] 
Very Easy.
