My 3 month old daughter had a heart transplant jan 19th due to Congential heart defects ? about a certain med.

She is on 8 diffrent medications and her being so young, she takes everything liquid orally. Well they also have her on prevacid to prtect her little belly from the harsh medications, but everytime we give it to her, she ends up spitting it up or puking all of her medications up at once. Does anyone know of any altertatives to prevacid that works just as well for infants that has a better taste or any ideas on how to change the taste so she will take it instead of puking it up along with all her immunosuppresents.?
