It is important for them for sure.
My grandmother...well...She was born in rural 1930s Kansas, The Dust Bowl was her young childhood memories! She had to grow up fast, but in all actuality she wasn’t the most fantastic mother... My mom’s father died when my mom was age 9, she left my mom and ran off to find another man since she didn’t know how to live without one.
Yes my closest “grandmother” figure is my aunt.

My mom, and her two “older” siblings were raised by her two older sisters and their children. I could have had a real grandmother figure but my dad’s mother never stepped up to the task. My great-grandmother was a much better figure, attended my 3° soccer games every single weekend.

My grandfather definitely did his best to be the greatest grandfather a girl could have though, before I lost him on Black Friday when I was 9. He tried to teach me to clean bullets, and reload them, and liked to microwave pop tarts while they were still in the wrapper.

I don’t really remember how to do those things anymore since it’s been so long, but I’ll cherish those memories.
Wow those were some big memories reappearing.
But moral of the story!!! It’s not so common anymore for young mothers, but a strong support system, and keeping everyone together is so important. They need those things to help them through those stressful times.
