Hospital bag planning question

Okay, I am planning what I should put in my hospital bag. We are 3 days into our final week in the second trimester, and I have a history of preterm labor, soooo I like to plan and prepare early. I am usually the kind of mom that uses what the hospital provides, but I am curious to know if the Frida peri bottle or one similar is actually as good as everyone says it is? I never had an issue with the hospital ones, but I am curious. Also, I have been seeing more and more moms using women’s diapers for postpartum rather than the pads and mesh undies. Are those worth it? Were they life changing as far as postpartum goes?
