1 month old projectile vomiting breastmilk

Pa

My 1 month old baby who is gaining and wetting diapers, has occasionally projectile vomited these last two weeks.

I noticed it’s after he cluster feeds in the evening. I tried pumping to slow my letdown. We see the pediatrician over it on Thursday. I’m worried it’s acid reflux my first born had it so bad he needed a feeding tube.

I’m working on burping him more frequently too. Anyone have a similar situation with breastfeeding?

Im so discouraged with breastfeeding right now. I got mastitis 1 week PP and I can’t get my supply to go down. Im uncomfortably engorged at times. I really don’t know how much longer I can take this. There’s a part of me that just doesn’t want to give up. 😩
