new pump parts?

Question

I've had my Medela pump ">breastpump for about 3 months now and have already had 2 pieces crack and need to be replaced. Is this normal to have to replace the plastic pieces so soon? I pump normally twice a day.

Answer

I pump 6+ times a day for the past 2 months without any issues.  I have a Medela pump in style advance.

Answer

I have been using mine for two months, pumping multiple times a day most days. I have not had any issues yet.

Answer

Which parts? I use a Medela as well and haven't had a problem (2 months in) but have been told that the valves wear out the quickest.
