Foods that make reflux worse?

Hi! My 8 month old is becoming a pro eater and pretty much eats whatever we eat. He is on Prilosec for his reflux and the dr is hoping to start weaning him off around 10 months (we just got some weight gain issues under control). Anways, his spitting up has been improving but I’m noticing some foods may be increasing his spitting up, or he’s spitting them up way after eating them (like 8 hours later). We noticed this so far with scrambled eggs (no allergies flair ups, just spit up) and now pineapple. Has anyone else noticed this? What are other foods that seemed to make the reflux worse? Thanks!
