No. Do not use the Mon Lait Pump if you have an active implanted device that could be affected by a magnetic field (e.g., a pacemaker or implantable cardioverter-defibrillator). 

Mon Lait Pump was made to fit inside a standard nursing bra, so the cup size doesn't affect how it works. If you are wearing a stiff, structured, or inflexible bra, you can use the Bra Adjuster to create additional room.

We recommend that you sit or stand. However, the Mon Lait Pump is designed to be flexible. It can accommodate other positions depending on the milk level in the bottle and where the pump sits on your breast. As long as the Mon Lait Pump functions correctly, you should be good to go in any position.

No, that isn't necessary. Mon Lait Pump should be firmly pressed against your breast with no gaps in between.
