Pumping but bottle feeding?

M • 💍🐶👶🏽🎀👨‍👩‍👧💕
LO has a very bad tongue tie, and my nipple is very inverted. We tried very hard to latch, but it just wasn't working and she was losing too much weight. 
Now I pump multiple times a day and have a good supply going, but I'm not sure if I'm pumping often enough. 
Can anyone help or offer advice?
