As with any interpretation of a text, one must remember that an individual's justification regarding a meaning of a line is simply that: an individual's reasoning. That being said, some may find other quotes which support Hester's Puritan parenting styles in The Scarlet Letter.
So you know, I have access to an E-text and cannot provide pages numbers for the quotes as you requested. What I will do is give you the chapter and paragraph number from which the quote is being taken.
The following quotes show a comparison to Hester's raising of Pearl in a Puritan fashion.
With nothing now to lose, in the sight of mankind, and with no hope, and seemingly no wish, of gaining any thing, it could only be a genuine regard for virtue that had brought back the poor wanderer to its paths.
The preceding quote is from Chapter 13. It is the last sentence of the second paragraph of the chapter.
The reason that this quote shows Hester's Puritan parenting skills is because the Puritans (believing that all people were sinners and damned) needed to live virtuous lives to insure their passage into Heaven.
The next quote that supports Hestor as being a good Puritan parent is found in the first sentence of the third paragraph of Chapter 13:
It was perceived, too, that, while Hester never put forward even the humblest title to share in the world's privileges,--farther than to breathe the common air, and earn daily bread for little Pearl and herself by the faithful labor of her hands.
This quote shows that Hester stripped herself down to the bare minimum- something the Puritan did to Christianity so that their religion was a pure one. This quote shows that Hester wished to do nothing more than show her faith through the work of her "faithful hands."
