I have one of these pumps that I used occassionally for my dd (who is 19 months now). I have a ds due in July so I took my pump out of storage to inspect it and found mold in the valve (soft silicone piece) and in the lid assembly. I can't find any replacement parts for this pump, so I seem to have two options. 1-bleach everything and hope that it gets everything clean or 2.-throw it out and buy a new one . What you do?
