I have nothing but admiration for your family values. The only toddlers I want running in around my house at my age (55) are grandkids (of which I now have 2).
And I’m quite happy they go home with their parents (my kids) most all the time. The occasional weekend, fine, full time, not so much. Been there, done that. Loved every (nearly every) minute of it. But the baton has been passed to the next generation.
Everyone makes his own decisions. My husband is 50 and I’m 47. We would prefer not to have a baby at this point in our lives, for health reasons and to support the needs of our other children. We’re trying to get two extremely intelligent slacker youth into college in the next 9 months!
However, we are open to life in the sense that we are neither contracepting artificially nor sterilized. If we conceive a child, either today or five years from now, we will accept that as what God wants for us, with the proviso that He knows best.
