Babies

In animal kingdom, we can see a diverse means of childcare. Some animals lay eggs, and the babies hatched have to find a way to survive themselves.  Most of them die during childhood, a few survive and reproduce babies.  In such case, mothers don't seem to care about the babies; however, at least mothers try to find the best spot for egg laying, so that the babies have better chance to survive.  In an extreme altruistic case, a mother spider gives up her life as she is willing to be a food for the hungry newborn baby spiders, ㅠㅠ.

Other egg-laying animals tend the eggs and then take care of the babies until they can move/fly, find foods, and defend themselves. The biggest challenge for the parents (or mostly mothers) is that they have to leave occasionally the nest to find foods for herself and babies.

Mammals, including humans, give birth to babies and mothers feed them with milk for a while. This kind of physical interaction establishes a tight bonding between children and mother.  It squeezes tears by watching a film showing that a mother animal is so reluctant to leave sick babies.  Such kind of mother's feeling for babies is universal.  This led me to believe that animals do have spirit, if we have it.  And I do believe that humans are not so special existence, just part of the mother nature.  =°|°=
