Child
A child is a young boy or girl in the care of parents, older than a suckling or an infant, but not yet an adolescent. "Children" are sometimes used as a name for a large group of descendants of one person, such as the Children of Israel, or even all human beings as the Children of Men. A child represents innocence and charity, where innocence is the willingness to be led, and charity is love. This is why Jesus blessed them and suggested that we all become like children in order to enter heaven.
Jeremiah 9:10-11
10
For the mountains will I take up a weeping and wailing, and for the pastures of the wilderness a lamentation, because they are burned up, so that none passes through; neither can men hear the voice of the livestock; both the birds of the sky and the animals are fled, they are gone.
11
I will make Jerusalem heaps, a dwelling place of jackals; and I will make the cities of Judah a desolation, without inhabitant.
