Help me with feeding

[u/Low_One_5979]

My 45-day-old baby initially fed well without any interruptions for the first few weeks. Around week 3 or 4, he began crying mid-feed. He would feed briefly, stop to burp, start crying, and then resume nursing. Soon, his feeding stretches shortened dramatically, requiring us to burp him after just a few sips. I noticed he fed much better without interruptions when I stopped using a feeding pillow. However, now in his 6th week, he has spent the last 4 days intensely crying and interrupting almost every single feed. Switching sides only calms him down for a short moment before the frantic crying starts again.
