my advice,
get over it! its a little dragon the size of your index finger. if you react and show him biting, gets rid of you and that pesky giant hand, he will keep doing it. whereas, if you show him biting, flaring and bearding has NO effect, he will give up. trust me, bites, beards, flaring and badgering from an adult dragon is FAR worse. at most he will give you a few scratches... he's tiny.
