Just to add another data point. This last year due to the shortage, we’re spending 200/mo on formula alone.
Even if direct nursing is going well, I highly recommend doing some pumping along the way from early on so that if/when she needs to be away from the baby for a few hours, it's not as big a deal.
Not everyone has an easy time of it though. They either can't produce any or not enough and the combination of this pressure and post-partum depression can be life-threatening. There's a lot more that goes into the decision to formula feed than cost.
