Nightime Pumping Questions

At night my LO's first stretch is around 6 1/2 hours, then we change and feed him and he goes right back to sleep for another 3 1/2.

I always nurse one boob per feeding so during the nighttime feeding, one side is already getting really hard and uncomfortable. By morning it is painful and my LO has a harder time latching, but once he does, he emptys it all like a champ. 🤣

I was pumping that side after the 3 am feeding, but I already have a very large freezer stash and I don't want to have to stay up even longer to pump because I have a harder time falling back asleep.

Will my body start to realize that I don't need to produce as much at night? Or do I need to stop being lazy and continue to pump? I just don't want it to affect the rest of my Supply
