Journey33

Hi everyone! Im a frequest poster on multiples and I recently started researching BF but I dont really know where to start.

First, is a hospital grade pump necessary? I noticed the medella is $1,500! Can anyone recommend a good one? Are there different types?

Second, is there any literature you can recommend for me to start researching in the right place?

Thanks in advance everyone!
