Yeah,if they don't go back up, before 6 months, tape them! I heard six months is the cut-off point! It worked for my little one. If that doesn't work glue (eyelash glue works) a little bit of paper bag inside of the ear, only after the hair has been shaved off of course. It sounds mean, but it is usually better than having your little one pull out the tape and her/his hair. Sorry, I could find only the picture of the taping.

Good luck. The glue worked for Chibi with his elephant ears! We kept it on until it feel off a week at least, or so! He was ok, but check your baby doesn't have any allergies to the glue by checking for hives, redness. With baths the glue wears thin and comes off, so don't worry!
