Breast milk supply at night?

[sadmum2017]

DS is 9 weeks old and has been gradually increasing his nighttime sleep and only wakes once or twice. Tonight he slept 8pm til 4am. Obviously I woke up engorged and after feeding him, I pumped from other breast. He still feeds 2-2.5 hourly during the day. Will has lack of nighttime feeding affect my supply? Should I wake up a pump through the night anyway?

I wouldn't pump through the night, that will just encourage your body to keep making more. You'll find your flow soon adjusts to his new sleep pattern, or that was my experience anyway. Congrats on your snuggly little one!
