I never thought of giving medication as it happens to most babies as they’re tummies get full and get used to holding down milk it happened to my baby but he was fine and it normally happened while changing nappy so I tried to be more careful

I think repeated reflux can causing minor burning of the throat with some soreness

Oh yes , when they were newborns. I will never forget the first time my daughter was born threw up her milk ( at the time hospital encouraged me to bottle feed ) and it was like fountain that I practically yelled frenzy for the nurses/docs. They came in calmly and said don’t worry it was reflux. I was very scared of feeding and many times I even held them over the sink to burp . One day someone told me to try putting your baby on a bit of a slant in the bassinet to relax them better and put small pillow underneath the base where her head is so it is lightly tilted. From then on I don’t know what it did but she never threw up after that . Tell this to your childhood nurse about it and if possible no meds as I think they are too young for that . Good luck .
