The two most valuable resources a child has is their parents’ love and their parents’ trust. Yes, both parties have a say in the future of both. Especially as the child grows and the relationship becomes more complex and reciprocal and less dependent and authoritative, good action on the part of either can make a big difference in developing these resources, and abuse and neglect can make a big difference in eroding these resources.
A child is entitled to their parents’ love by birth, and if they do not have it, or lose it, they have lost almost everything. Life will be hard. Not impossible, but their greatest asset will have been lost. At a very young age, touch is the chief signal to an undeveloped sensation and mind that that love exists. Lack of touch for babies of many mammals will result in death, regardless of provision.
