Anyone’s baby on Prevacid?

My 10 week old has been on Pepcid for a few weeks for his silent reflux but the last few days it no longer works and he is back to screaming during feeds and barely eating (went from 24oz a day back down to 15oz)

So the dr prescribed him Prevacid to try and we just got him on it today. First off, is there any easier way to give him these dissolvable tabs? So hard. And is this med working for your little ones? The not eating and being in pain is so sad :(
