Night time feeding


So my son is 5 & a bit weeks old. He recently started waking up less at night which is amazing. But I’m worried about my supply. He’s doing 5h stretches. He’s every 3h on the dot or sometimes 2h, when it’s daytime lol, little pork chop doesn’t miss a meal then.

My fear is that when he starts sleeping even longer, will my supply drop? Should I be pumping? I really want to be successful breastfeeding for as long as possible as I had to stop our journey a lot earlier than anticipated with my first & it was very upsetting. Any advice?
