Scarlet Letter question

The child Hester held in her arms was seen as another token of Hester's shame.

When the young woman--the mother of this child--stood fully revealed before the crowd, it seemed to be her first impulse to clasp the infant closely to her bosom; not so much by an impulse of motherly affection, as that she might thereby conceal a certain token, which was wrought or fastened into her dress. In a moment, however, wisely judging that one token of her shame would but poorly serve to hide another, she took the baby on her arm, and with a burning blush, and yet a haughty smile, and a glance that would not be abashed, looked around at her townspeople and neighbours.
