Want to transition from bottle to breast

I had my son at 35+6 and he breastfed amazingly a few times. But then he needed to spend time in the NICU and it messed breastfeeding up for us because they needed to give him bottles. Now he will do it for about 5 minutes at most but doesn’t seem interested 💔 I’m hoping SO bad that he will transition back to the breast. I was so excited that he was breastfeeding well 😢

I do plan on reaching out to a lactation specialist but does anyone have any tips? Or go through something similar?
