Told or Known

…discussion of whether couples choose to learn the sex of their baby before he or she is born, a number of you said you wanted to keep the secret as long as possible, because the moment people hear “boy” or “girl” they begin to make assumptions about a child. One couple in Sweden decided to take that logic a few steps further, and are refusing to tell anyone whether their toddler is a boy or a girl.

Seems a bit reductio ad absurdum to me, and probably pretty confusing for the child.
