FTM Question: pumping during a bottle feeding?

Kdrake8

I have been EBF so far. However, DH and I were talking about trying DD on one bottle per night, so he can do one feeding. If we do this, do I need to get up and pump at this time as well, to maintain supply? Or would I be ok skipping it?

 If I do need to pump, how long would you suggest pumping? DD normally eats for around 20 minutes or so each time she nurses.
