Top 10 Animal Moms

The highly intelligent orangutan is the ultimate do-it-yourself mom. She spends nearly all her life high up in the trees, where she builds a new nest every single night from branches and foliage, fashioning more than 30,000 homes in her lifetime! She also never puts her babies down, generally nursing offspring until they reach the age or 6 or 7 — that's the longest dependence of any animal on Earth. For the most part, males come around only to mate, and even the baby boys break away more quickly from their mothers than their female counterparts, who often stay longer to learn child-rearing skills.
