Yeah, I was going to say, my grandmother took care of me & my sister while my parents, in their 30s, were at work, or if they needed a night out. This was in the 80s, so it's not anything "new" to 30-somethings.
One of the new things with grandparents today is divorces.
Because all of my child’s grandparents are divorced they are not able to retire / and have to work. This prevents them from being able to offer the same kind of child raising assistance as grandparents that stay together.
Same here, my grandmothers and great aunt raised me when my parents had to work. In the late 80s...it’s not uncommon, especially in immigrant families. It is seen as a good thing, not something to be ashamed about.
