confused !!!!!!!!

Ok, I am confused on something, in which it don`t take much. Anyway, when you have a child it is either a boy or a girl , that child does not make the decision on whether it wants to be a boy or a girl....GOD does . Today on the Today show, their is a couple that is keeping the sex of their baby a secret and letting that child make the decision of whether the child wants to be a girl or a boy. The child is only 4 months old....I just wonder how old this child will be when the desion is made. This just makes me a little upset and wonder what this world is becoming in too. Letting the child make the decision on whether it wants to be a boy or girl is absurd, the child is either a boy or a girl, there is no getting around this.
Letting the child make this decision is crazy, ....Let`s see should a child make the decision whether it wants to learn to read or write....or should it make the decision to climb on top of the roof and jump off..... I am just a little confused on this can anyone out there help me out on this....?
