Slim's advice is pretty solid in regards to them growing out of the nippy stage.

I've had more than a few nippy babies that grew out of it within months. In the stores, we often have super nippy little babies that calm down immensely within weeks of getting home and set up in their own little cage and left alone for a bit. So let yours get settled in, don't mess with it, and once it's fed a couple times for you, try handling it a little bit as the Serpent Merchant suggested.

The aspen should be easy to maintain for the most part. Spot clean poop, and about once a month switch it out. If you find that it is molding or mildewing before then, consider switching to cypress mulch or orchid bark, both of which can handle higher levels of average moisture than the aspen does.

And last but not least...another girl snake keeper here! Not just snake keeper, reptile store manager! Most of my relatives are like your family, and while they may not like the scaly beasts very much... by now they do appreciate it somewhat. Even my terrified-of-snakes grandmother asks about how my babies are doing! Give it time, they'll come around. Enjoy your new pet!
