Wanting an over supply - help!

So I'm slowly getting there - I've been having to combine feed between milk and formula because I couldn't keep up and she was suffering with Jaundice.

Weve now blitzed past that stage but she had an appetite! So were still combine feeding

I'd love to get to a place where I over supply, I'm in a position where I can sit and pump regular, I'd like to get a freezer stash going and donate to our hospital.

I need to get more rigid in my routine (aspecially through the night)

I've been having babe on each boob for 10 minutes then pumping, I try and do this every 3 hours but still very new....

How do I get a super supply???

Any hints / tips / tricks / routines that have worked wonders? Thank you 💜💚💙💛🧡
