People say: “You get used to good things quickly”. And it is true that when a child is taken from a children’s home or a child’s home, it is clear to everybody that now a real life will start, in a family, warmth and love.
The child does not believe his happiness, everything is new to him, everything is interesting, and emotions can fill him to the edges. Foster parents can also experience euphoria (something similar to the birth of a child) – all obstacles are overcome, worries experienced, and finally the long-awaited moment.
