...In bird and mammal biology, altricial species are those whose newly-hatched or -born young are relatively immobile, lack hair or down, and must be cared for by adults; closed eyes are common, though not ubiquitous. Altricial young are born helpless and require care for a comparatively long time. Among birds, these include, for example, herons, hawks, woodpeckers, owls and most passerines. Rodents and marsupials are altricial, as are cats, dogs and humans. Read full entry

ALL Mammals have altricial babies. There is no such thing as a precocial baby Mammal, because all their young MUST have a parent to survive and CANNOT take care of themselves. All Mammals nurse their young (this is what makes them Mammals) and therefor need their mothers, not only for protection, but for milk. |

First, if a doctor says something you don't understand, don't be afraid to ask them what they meant. In this case, I can only guess that it means you can't care for yourself yet. He or she might mean emotionally and not physically. |
