From the perspective from Sweden, the problem is not that complicated as long one agree to a few core concept. Children has rights that supersede that of their parents, and the parents are usually the best adults to take care of their children but not always.
If deportation of the whole family is the best for the child, then you do that. If placing the child with relatives or foster care is the better choice, you do that. Children aged 2, 4, and 7 can't "game" the system, and so its the adults job to take responsibility and find a solution that address the rights of the child.
