>>21470511 (OP)It's really not that good. Breast milk is like, cloyingly sweet already. Honestly, freeze it and hoard it. She might stop producing a few months from now, while your baby still needs milk, and if you're completely out you'll have to switch to formula, which is full of bullshit and costs a fucking shit ton.
We barely made it, with our son, he had just started to eat solids when our stash finally ran out; my wife had stopped producing a couple of months prior to this point. When we did finally run out, he was old enough to transition to cow's milk, small amounts of fresh juice, and water, getting most of his calories and nutrients from solid food.
