Trying to latch baby 😓

La

So my baby was born at 35 weeks and had four day NICU stay. I knew it would be challenging to get him to latch on since he was feeding from bottles. My hospital has lactation services there and I plan to go.. but giving it more time before I get him out of the house. I’ve tried getting him to latch and he has a hard time. Or he will latch and suck but pull away. I’m not 100% discouraged because I’m pumping and he’s still getting my milk. But I really want that bond with him by nursing. Any other tips or tricks I can try?
