oh i have no expirience assist feeding either. just use the head of the mouse and your fingers to open the mouth of it. you pesonaly can open his/her mouth by putting your thumb on top of the head of the snake, and your index finger on the middle of the lower jaw. and gently apply pressure on the lower jaw with your index finger. then roll your index finger down the the jaw twards the snakes body. (kind of like the popping method)(sexing) this will open the snakes mouth just a little. but remember to be gentle. then us the moues head to push down on the lower jaw and allow it to hinge onto the snakes teeth. its a lot easyer than it sounds. trust me!good luck. you can switch the way you do this if it makes it easyer. (thumb on top index on bottom) what ever works for you.
