Anyone have a similar experience?

My little one is in the NICU (born at 29 weeks). Shes now 33 weeks and has her feeding tube. She just started experiencing some reflux after feedings where she’ll have some apnea and drop her heart rate and oxygen. She also threw up all over me today after her feeding. They say she’ll outgrow it and that it’s due to her being premature but anyone have the same thing?
