>> getting shots. >> medicine tastes disgusting. >> disgusting? >> yeah. when i have a cough. >> i hate getting stitches. >> reporter: yeah, the doctor's office isn't always fun. either kids are there because they feel sick or it's time for a vaccine. but parents, you can make it better. for example, don't say out loud, "he doesn't like it when you look in his ears." you remind him of the last time, setting this up for failure. and don't tell them if they're bad they'll get a shot. that's mean. >> you want to set up this whole experience as a positive experience. you don't want medicine to be perceived as bad. you don't want the doctor or the nurse to be perceived as the punisher. >> reporter: then there's avoiding the wait. >> you have to wait and wait and antibiotics. >> have you ever had to take an antibiotic, a medicine for your ears?
