i've been really stressed these past two days and it's affecting my pumping and now eden isn't sleeping well i think because i'm not making enough milk or something. so we have to use milk i had saved up in the freezer, but we are using it faster than i can replace it and i really hate the idea of supplementing with formula. i feel like i'm failing.
