Analysis of To his saviour, a child;a present, by a child

Go, pretty child, and bear this flower
Unto thy little Saviour;
And tell him, by that bud now blown,
He is the Rose of Sharon known.
When thou hast said so, stick it there
Upon his bib or stomacher;
And tell him, for good handsel too,
That thou hast brought a whistle new,
Made of a clean straight oaten reed,
To charm his cries at time of need;
Tell him, for coral, thou hast none,
But if thou hadst, he should have one;
But poor thou art, and known to be
Even as moneyless as he.
Lastly, if thou canst win a kiss
From those melifluous lips of his;--
Then never take a second on,
To spoil the first impression.
