Final answer:
Children should not work at the mill according to Lucy Larcom.

In her writing, she states that the mill life was not suitable for a child, and she and her fellow child workers were happy in knowing that their employment was only temporary. Therefore, based on her perspective as a mill worker in the late 1800s, children should not work at the mill.
