Hello, and congratulations on your new-found happiness!
I am a 53 yr. old mother to an energetic 5 yr. old! He is healthy and happy, but he also has been diagnosed with autism spectrum disorder. He is very high-functioning, smart, and extremely social, but there are delays (speech), that have made it necessary for him to be in a hadicapped pre-school program for the last 3 years.
There are a number of risks involved with pregnancy at a "mature" age, not the least of which is the very real possibility of multiples! Certainly as we age, so do our eggs, causing the risk for Down's Syndrome, or other birth defects to be much more likely.
I would certainly address your questions and concerns with your doctor, and good luck with whatever you decide.
P.S. I am also recently widowed, so I am facing my middle-age years as a single mother. My son keeps me young, and he is my reason to keep going strong, but I struggle to maintain my stamina in the face of all his energy. I also work full-time, so I am grateful when the end of the day finally arrives! C. G.
