"Morning Song" is a sneak peek into the very first moments of a family's formation. We witness as a woman goes from being a single person to being a mother. Presto! We've got a family. Funnily enough, though, not everyone is immediately overjoyed at the thought of spending their lives with a small, screaming bundle o' joy. Despite the tension that we see in the poem, by the end, we feel that the new family is forming strong bonds.
The speaker's feelings for her child are entirely natural.
The speaker and her child have formed a strong mother-child bond by the end of the poem.
