Tegan's condition

The Pediatrician called and told us that Tegan has a bladder reflux condition that she should outgrow. However, to avoid further infections which could ultimately damage her kidneys, she will be on a low dose of antibiotic for one year. That seems easy, but Tegan hates that antibiotic and spits it out, so we will have to find a creative way to incorporate that into her day. Any ideas?
