Breastmilk Stash

Br

I would like to breastfeed my baby for a year, maybe longer. She is 3 months old. I have built up a decent chest freezer stash of breast milk so far. But Since it’s only good for a year, do I stop breastfeeding and switch to bottled breast milk so my stash doesn’t go to waste? Or slowly work in bottles with the milk that will expire sooner and keep breastfeeding?

What have you moms done?
