Help! Milk drying up, need to bring it back ASAP!

So these past 10 days I was going back and forth to the hospital cus my FIL was hospitalized and he unfortunately psssed away. During this time I wasn’t able to pump as much or BF as much. I couldn’t bring my baby with me. And I’m now down to pumping maybe an ounce to 1.5 oz per session. And my baby’s is having a hard time latching.

Any suggestions on what I can do to bring it back ASAP?

So far im doing the following:

1. Power pumping 2-3x a day

2. Hydrating- gallon a day

3. Honest co bf vitamins

4. Homemade lactation cookies with brewers yeast

5. Trying to bf and get my baby to latch again. She’s only 5 weeks. I can’t let my supply dry up. It wasn’t great to start with but it was enough. Now it’s not. 🤦‍♀️

TIA!!
