Yes one main tip: PERSISTANCE! And try to end things on a positive note, meaning the monitor was calm and relaxed before being place back in its cage. Also do not apporach from above or make fast movments. Handle for a half hour once a day.(Twice is better) Do NOT backdown from a bite, or other defensive behavior as they will learn that, that behavior can get them what they want, to be put back in their cage.
As for handling make sure you support his body and allow all of his feet to be in contact with you, make sure your wear long sleeves when doing this, until he tames down he is going to scratch but when little thats not a problem. Also your monitor is displaying normal behavior for a baby, they will calm with age and handling. NEVER EVER hand feed a monitor, this is the easiest way to get a serious bite as when it comes to food its bite first ask questions later, feed witrh tongs.
