Little Lamb God bless thee. In the first stanza, the child asks the lamb if he knows who made him. This can also be seen at another level, with the child asking where innocence or the good in life comes. The next four lines give the feeling of being young, free and innocent. This higher spiritual thing gave life and asked the lamb to feed.
Young children have so much life.
The stream and the meadow bring the feeling of being young and free. This to me seems to infer that the lamb is white because white can be described as being bright. If the lamb were black, the word bright would not have been utilized. White is considered a color of purity and innocence which goes along with the theme of this poem. Children have tender voices and often people enjoy the cute innocent things that come out of their mouths.
