Gwendolyn Brooks's "the mother" is a poem narrated by the eponymous mother. The mother reflects on the abortions that she has chosen to have and on the lives of the babies that were never born. In the second and third stanzas, the mother addresses directly her aborted babies, and she apologizes for all of the experiences that she has denied to them.
Throughout the poem the speaker lists all of the things that the aborted babies will never be able to experience. They will never, she says, be "silence[d]" or bought "with a sweet," and they will never cry "baby tears," play "games" or experience "loves...tumults...marriage...[or] aches." They will also never "giggle...or plan...or cr[y]."
This list of plentiful things, or experiences, which the speaker feels she has denied to her "killed children," emphasizes the guilt which seems to torment her. She feels that she has denied to each of these "killed children" the rich collection of experiences, good and bad, which comprise a typical life.
At the end of the poem, the speaker assures all of her unborn children that, despite denying to them all of the aforementioned experiences, she, nonetheless, "loved [them] all." In the final stanza she repeats the word "loved" three times, and the very last line of the poem is simply the word "All." The fact that she pointedly emphasizes her love for these unborn children makes the reader realize just how painful it must be for her to recall the list of experiences that she feels she has denied to them.
