Pumping at night

At night my 7 week old has started to go for longer stretches of sleeping which makes my boobs SO full. So after he eats and goes back to sleep, I have been pumping for a few minutes to relieve them, but I know that makes my body think I need more milk..... so do I deal with my boobs being full a few nights so they adapt to his needs? Should I just pump a little less each night? Or just keep doing what I’m doing? (I do like having extra for storage) Any tips?
