Liz, I don't know the exact ages of your children or you, but don't give up! 15 1/2 years after the last of 3 grandchildren were born (that would be my Helen), my parents now have a new grandson, my brother's son. My parents are 72 and 74 and they are keeping the baby every day while my brother and my sister in law work. They are having the time of their lives!
