"The Nurse's Song" by William Blake Analysis

"The Nurse's Song"
When the voices of children are heard
on the green
My heart is at rest within my breast
And everything else is still

Then come home my children, the sun
is gone down 
And the dews of night arise
Come come leave off play, and let us away
Till the morning appears in the skies

No no let us play, for it is yet day
And we cannot go to sleep
Besides in the sky, the little birds fly 
And the hills are all cover'd with sheep

Well well go and play till the light fades
away
And then go home to bed
The little ones leaped and shouted and 
laugh'd
And all the hills ecchoed.

The poem "Nurse's Song" by William Blake features a group of children playing outside in the hills. A nurse is watching her children play out in the fields. She calls for them and they protest just like any other kid. They want more time to play even though its dangerous to be outside late at night. She lets them stay longer though.
The form of the poem has four quatrains, rhymes ABCB and contains an internal rhyme in third line of each verse. This poem does not suggest any sort of alienation. The nurse feels that she wasted her youth and calls the children home and that they are wasting their time playing and should be sleeping. Since the sun is in twilight it suggest the youth have already become sexually active and will now reap the consequences envisioned by the nurse. This nurse is cynical. Upon hearing the voices of children she "turns green and pure" on image. This reflects her missed pleasures back in her youth and she becomes very aware of it.
At every quatrain Blake makes emphasis on "Come come", "Well well", and "No no" to sound like a mother like figure to the children. The children's playing brings her peace.her tranquility resonates to the natures stillness and perhaps that is why she had to give them another chance to stay outside and play.
