A、Because they already understood what it means to be a baby for blood parents. B、Because they have developed a subconsciousness

W: It’s sure to say his transition to living an adoptive home may be difficult, isn’t it?
M:(6)Yes, it proves difficult as he adjusts to new surroundings and caregivers because, by the age of 18 months, he has already begun to develop a sense of self in relation to others. On the other hand, he is past the crucial age of 7 to 12 months.
W: Why do you call this period the crucial age?
M:(7)This period is crucial because at this time an infant may sustain the most severe damage to his mental and physical development if deprived of mothering by one significant individual. Now it seems as though he has to start over: his protesting may give way to despair as he yearns for people who used to be in his life.
W: Then it is essential that(8)the adoptive family offer as much affection and security as possible to reassure the child that he is safe, that they are reliable sources of loving care, and that they will help him through this difficult stage.
M: One thing we need to note is sometime a child may continue to suffer from separation anxiety in spite of these actions. Although he may not mind the actual separation from his mother when he goes to play school or day care,(9)he may become obsessed about the time when his mother is supposed to pick him up at day care or kindergarten: tardiness may provoke fears about car accidents or death.
W: Some psychologists believe that a child who is given more affection is sometimes more strongly attached and therefore more prone to separation anxiety than some of those who are treated more roughly. Does such statement hold water?
M: That may prove right.(10)Since such "dependence" in the well-loved child is outgrown and later provides the basis for a stable independence, it would be a mistake to suppose it to be pathological. On the contrary, the capacity to experience separation anxiety can be regarded as a sign of the healthy personality.
W: An adopted child, then, has at least an average chance of successful individuation, assuming he is adopted by loving parents. Thank you, Sean. Thanks for talking with us.
