Fastest way to adopt a newborn

I am single and adopted internationally when I was 51. My daughter was 18.5 months old at the time, and is 16 years old now. Frankly, I have not felt that parenting at my age has been particularly difficult. Yes, I've had less sleep, less time for myself, and less money than I would have had if I hadn't adopted, but frankly, those things pale beside the joy I've had in parenting my daughter. I know that, domestically, many birthmothers do not choose older couples, as the couiples may be as old as their GRANDparents. Still, it is not impossible to find a birthmother who is open to an older couple, especially if you do a private adoption. So even if it takes more than a year to complete an adoption, I would say, "Go for it!" Sharon
