Ok, I always rinse my breast pump with super hot water as soon as I use it. I also wash with soap and water every few days. I should have known better, but there was a part of the pump I was apparently not getting clean - between the plastic and the diaphragm part. It started dragging today and I took it apart thinking I needed to replace something and saw a buildup of milk gunk. And one side had a brown stain in the "head" part of the plastic/diaphragm part. Of course, I freaked, washed everything and then boiled everything.
I am so terrified that I've made my 4-mo. old sick! I feel like such a terrible mother! How would I know if I have in fact made him sick?
