When my baby was on formula she seemed to spit up more. Does formula or breast milk trigger more reflux?

First, let me be clear: reflux in babies most often comes from immature muscle development. So the underlying cause is usually not the type of food but the stomach valve not fully closing yet.
That said, breast milk is generally more advantageous for reflux. Breast milk is digested faster in the stomach and empties more quickly. After feeding, there's less chance of milk coming back up, and this is connected to faster digestion.
Formula is heavier to digest and stays in the stomach longer. When given in large amounts or too quickly, this can increase stomach pressure and make reflux more noticeable. Also, some babies have sensitivity to cow's milk protein, which can worsen reflux-like symptoms.
Another possible reason for the difference you noticed might be flow rate: Formula from a bottle often flows faster and more continuously, which means your baby might swallow more air and her stomach fills too quickly.
If your baby seems uncomfortable, make sure to review feeding position (upright after feeding), frequent breaks, and sleep position. If concerns continue, definitely tell your pediatrician.
