I would have loved some donor milk for dd2 when she was in PICU. I might have slept for more than 30min in over a week but I didn't have that choice.
Let mums chose what's best for their family. For mine - it's my bm or donor bm as a second choice. Since I'm currently out of lactating cousins - I don't have that choice at this point.
For you - it was formula. And that's fine. Because it was the best choice for you and your baby.
