Moms that are exclusively pumping... question!

Heather • 💍 3/17/16 💙 12/19/16 💗 5/23/18
How many times a day/night are you pumping at this point? How long is your lo sleeping at night? 
I have been pumping 6 times, once overnight between 7:30 pm and 5:30 am. Our little guy just recently started sleeping through the night.  I would loooove to skip the middle of the night pumping session and get 8 hours of sleep, but I'm so scared my supply will drop too much if I do that. What do you ladies think? Any of you have experience with this?
