1. It continues after birth

"This is one of the most dramatic distinction between humans and other mammals (including primates). In all precocial mammals other than humans, at around the time of birth there is distinct slowing down in brain growth relative to body growth. In altricial mammals, the switch to diminished brain growth occurs at a developmental stage comparable to birth in precocial mammals. In humans, substantial brain growth relative to body growth continues for approximately a year after birth before a marked slow-down occurs. Because of this human neonates are unusually dependent on parental care in comparison with other primates for the first year of postnatal life, and sometimes labeled as "secondary altricial".
