Most parents find responding to young children's questions about where they came from a bit tricky.
It is not surprising that adoptive parents have particular worries about how best to answer them, but the sooner the children are told, the better. It would be less than helpful for a child to learn of his or her adoptive status from other children. The meanings young children give to the facts of adoption may be a bit confused in the beginning. It is all right to indicate that it will get clearer later on. Threes and fours are unlikely to be concerned about the reasons their biological parents did not keep them and are not as likely as older children to ask for information about them.
