Lots of questions

My baby will be 6 weeks on Friday

I have inverted nipples my right side is still inside but I have managed to be able to pull it out when I can my baby couldn’t latch and at the hospital the nurse brought me a nipple shield.

Ive been using the shields but I realized in this group that maybe they were too small and I have tried the bigger size and I believe those are my sizes I did measure.

I feel like my baby eats a lot and since I thought I didn’t fill her I kept supplementing with formula.

She’s about to be 6 weeks and she takes 4 ounces every 3-4 hours.

When I pump in the morning I can only get 2 ounces from both breast’s and throughout the day I’ll get half an ounce from each breast

She gets extremely frustrated when she’s hungry and can get enough flow from my nipples what can I do to make it better for her to nurse.

I’ve read that I shouldn’t have been pumping so early on but the LC at the hospital urged me to get a pump and pump as much as I could through the day.

Just looking for some tips Should I be pumping still do I need to changes something ?

I am drinking mothers milk tea in the morning, drinking water making sure I eat a balanced meal. Baby can latch on with nipple shields.
