Low Milk Supply

Samantha
Alright ladies, I need some advice. My lo is 8 days old now and latched very well the first 4 days and then she just stopped. She's latched for a few seconds then she would fuss and refuse to latch. So now I am pumping and bottle feeding but I am not producing enough milk to feed her. So I am supplementing with formula when needed. 
What can I do to help increase my milk supply?
