The author treated 14 child patients during her pregnancy. Many of the children were unaware of the pregnancy unless told. Allowing children to discover their therapist's pregnancy has the major disadvantage of failing to adequately prepare them for the separation at the time of delivery.

Quotations from the Article

"A therapist's pregnancy is a part of her life she cannot conceal from her patients."
Regarding the issue of whether to relate this news [pregnancy] to patients, the common teaching is "it is preferable to assume the pregnancy is noticed."

Dr. Callanan came to the opposite conclusion for children: "In my work ... during my pregnancy, telling the children seemed far more beneficial than is conventionally taught. First, it allowed them a prolonged period to work on the issue of separation [due to] maternal leave. Second, it gave the children a special feeling of sharing with me rather than giving them the sense that the adults had kept a secret from them."
