GDiapers

I have a gdiaper order on its way to us..newborn and size one. I also have Flip one size covers with prefolds &flats for inserts...but felt like it’s just too much fabric etc going on with a newborn. Gdiapers recommends only using their disposables with the newborn size to keep things trim but am wondering if anyone has any insert suggestions for newborn and then inserts for beyond newborn stage. I am ideally looking to stay away from microfiber and go with maybe a bamboo or hemp but having a hard time finding ones that don’t have microfiber...also in a small enough size to fit a newborn diaper.

Soo looking for suggestions on inserts for newborn and inserts for beyond that stage. Again avoiding microfiber if possible and if you have gdiaper experience please let me know what’s worked for you :-)
