Final answer:
Babies can fully use cutlery around six months of age.

Babies can fully use cutlery around six months of age. At this stage, infants have developed the ability to pick up objects and transfer them between hands. They can sit up and their vision has improved. The ability to use cutlery is a milestone that indicates their fine motor skills and coordination have developed enough to engage in self-feeding.
