Look at all the women who are taking ethically dubious routes to parenthood (surrogacy, donor eggs) because they waited until too late to have children. And if anyone points out the ethical concerns, they try to shut the discussion down by playing the "you don't understand the pain of infertility" card, as though there's no way they could possibly have known that fertility declines with age.
Your daughter is taking responsibility for her own fertility and having a baby at the healthiest point to do so. Good for her.
