Need to pump at night?

Frances

My little one is 2 months and she’s been sleeping 8-10 hour stretches without waking (woo-hoo). I’m exclusively breastfeeding, and I had a low supply at first and had to supplement her with formula for the first month while working with lactation consultants to get my supply up. It’s comfortably feeding her now, but I am concerned about going so long without emptying at night. Will this possibly jeopardize my supply? Do I need to wake up once and pump? She eats every 3-4 hours during the day.
