Scientists from the University of Cambridge have found that learning this in preschool can be beneficial for the souls of children born by a surrogate mother or by donation of eggs or sperm. The research was published in the journal human reproduction.
Researchers followed 65 British families with children born through assisted reproduction from infancy to age 20. They compared these families to 52 British families where children were born and bred naturally.
They found that mothers who disclosed the parenting of their children up to age 7 scored slightly more positively on the family relationship quality test. For example, only 7% of mothers who talked about parenting to their children before the age of seven and 22% of mothers who spoke about their parents to their children after the age of seven reported relationship problems.
After the age of seven, 50% of the children whose résumés were told reported that there was a problem in the family. Only 12.5% of children whose origins were told before the age of seven reported problems.
Scientists have stated that previously the existence of a genetic link was believed to be very important and without it the relationship could not develop well enough. Their work refutes this hypothesis.
