Everything will be just fine. My wife, God Bless her, was an OB nurse for 44 years and loved her babies coming into the world.
Now here is YOUR problem. You will lose two of your best hunting spots and your wallet will be much thinner, lol. I know by experience our son had 7 kids and they are still working me and I love every minute of it. I cannot describe the joy you are going to receive in your heart when your grand kids arrive.
