How is parenthood portrayed in The Distance Between Us?

The Distance Between Us was written by Reyna Grande. It is a story about a Mexican girl's upbringing in both Mexico and in the United States (as an undocumented immigrant). The story centers around a strange family unit that is missing its parents, who move to the United States to try to make a better life for themselves. They leave their children behind. One of those children is the main character in the novel, which is written as a memoir.
As a result of their parents' departure, the children feel unappreciated and disliked. They feel abandoned by their parents. Parenthood is portrayed as an unwanted burden in the sense that the parents feel like they need to neglect their duty to raise and care for their kids to free themselves in the United States to pursue their own dreams.
This sense of neglected parental duties becomes most pronounced in the memoir when the father announces that he will not be returning to Mexico to raise and care for them ever again. So the promise of opportunities in the United States was more valuable to the parents than their own parental duties, and the novel makes parenthood seem like an unwanted burden.
