Yeah I underestimated with the breastpads. I packed 6 for the hospital. I ended up going through a box of 60 haha
I was given two boxes of 40.
I ended up using ... 2. Breast pads, not boxes.
The baby eventually got mobile and found them (my partner was using the boxes as speaker stands), decided they were fun to empty and unwrap, and that was the end of them.

I didn't buy any this time but as above, I just got a box in the mail so we'll see ... I went through them with DD#1, never leaked with #2.
