Children, generally up until puberty, have a protective bubble which shields them and which filters out the kind of psychic energies that may pass through them. They live within the grace of God, so to say.
For babies this effect is much stronger. Compared to adults, the consciousness of young infants is more outside their bodies than inside. The physical body is a focus point for consciousness, and as the body grows more of that consciousness may inhabit it.
This also means babies in general are very psychic, but don't have a purpose or structured method to consciously use it by. A psychic baby's almost only concern is to exist within a state of love.
If a psychic baby grows up in a way that enhances rather than cuts off of this psychic connection, in general he or she will experience fewer difficulties for living a balanced, fulfilled and happy life.
