Splitting up of families of US born Natural Citizens

This woman (undocumented worker) lost her son because the judge couldn't (or wouldn't) find a way for her to keep her family in tact. While she is encarcerated, her son was adopted to another family. It seems to me that the judge deemed the family was not good enough. If we can find a way for Elian Gonazales (not a US citizen) to be peacefully and rightfully reunited with family, how come we can't do the same for a US citizen? There had to be some family member somewhere in the world willing to help until mom got out of encarceration, or some foster situation that could have worked out. These are some of the unintended or unconsidered consequences of sending undocumented workers home without their children, at least let them gather their family and keep the family together. If she gets her son back, he may not speak the same language. It could drag on for years in appeals, that does no good for immigration, the child, and either family after fighting over the child who will have been raised in at least two families, no one wins.
