Pump Issues

First of all, I'm a mom of 7. I've nursed them AND used a pump. My problem is that I have never used anything but a manual pump.

Well, fast forward to number 7, and having exclusively BREAST fed him for almost a year with no pumping... I can only get milk from my manual pump and not the electric. And it's not much right now but I know how to increase. He is almost a year (NEXT TUESDAY! 😁) and is very healthy and has plenty to drink.

I just don't know why the $250 electric pump won't make my milk let down. Any ideas??

(Yes, I st there a while and yes, I turned it all the way up..)
