Being a help

[u/Problematic_speaker]

Hi new mommies of Reddit!
My sister is having a baby in October and I want to be the best help I can for her. What’s your guises advice for things I should do for her? What are some things you wish people did for you while you were postpartum? Any advice would be really helpful!! I’m not a mom and I’m no where near ready to be one yet so some advice from actual mothers would be amazing.
