Fun fact: We are all gestated twice. Our maternal grandmothers gestate the eggs that will become us and our birth mothers gestate those eggs once they are fertilized.
Literally, a grandmother's health and lifestyle choices during her pregnancies can have direct impact on her grandchildren decades before they are born.
@Remixedcat Hopefully she wasn't pregnant with your Mom at the time, and was able to regain her health before becoming pregnant.
I think of my grandmother pregnant during the Great Depression with my mother and think that it could account for much that I see thru the last 3 generations.
