Breastmilk storage?!

Tanya
Hi there,
What kind of method you use to storage your breast milk?
Bags, plastic bottles, glass bottles, others?
I'm trying to figure what works best, and I kind of would like to used glass bottles, but I was reading online not all glass bottles are safe, they need to be an specific kind.
Any suggestions?!
THANKS A LOT, from my little prince and I 😉😃
