4 days old still not latching

Hey so I'm new to the group and I'm getting really discouraged with breastfeeding. I was able to get my baby to latch a few times in the past but due to his high bilirubin level and me only making colostrum - I was forced to supplement in the hospital with formula. My milk has come in and I am pumping a huge supply but am sad/upset that my baby will only take from the bottle now. I feel like I have tried everything - different positioning nipple shield sat with him for over an hour trying to make him latch. Does anyone have any advice or a similar situation with a success story? I have another appointment with a lactation consultant tomorrow but am not feeling very hopeful 😔
