Baby wont latch

Channy • Mom to an angel above and a handsome man.

Any ideas on how to latch baby onto breast baby was sent to nicu after birth and got bottle before breast ive been trying to latch him for almost 6 weeks and he would latch one day n then dont the next day so he has maybe latched 5 times out of the 6 WEEKS ive tried nipple shield and no help for long. I also pump when i can and not as much because he eats a lot he can eat from 3-4 oz per feed and sometimes 2-3 oz. please help and give ideas or even more ideas to increase milk while only pumping. Ive tried mothers milk and fenugreek suppliments
