Welcome to the BTS forums! Congrats on finding an amazing future pet for your family, and thank you for doing some research before buying.
Please read through the caresheet for the basics on BTS keeping:
http://bluetongueskinks.net/care.htmI would suggest you have any older kids read through as much as they can as well.
For what to feed:
http://bluetongueskinks.net/foodchart.htmlI would also suggest that you get your skink from a breeder rather than trying to find someone near you. People selling at expos rarely seem to be very knowledgeable on the skinks they sell unless they mainly breed BTS, same with pet shops.
When you buy from a reputable breeder you can be much better assured of getting, not only a healthy quality animal, but all the support you'd need in the beginning, and be much better able to trust what is said about the baby, the parents and the lineage.
Here is a list of our recommended breeders:
viewtopic.php?f=5&t=19635If you go to bluetongueskinks.net on the left side you'll find details of the different species and subspecies, but as you are in the US you will be most likely to find Meraukes, Indonesians, Irian Jayas, or Northerns. With a Northern you are guaranteed a CBB (Captively Bred and Born) animal regardless of its age; with the gigas species (Meraukes, Indonesians and Irian Jayas) the animal, unless purchased from a breeder, may very well be WC (Wild Caught). The other species, if available at all, will be harder to get a hold of and more expensive.
As luck would have it the Northerns, the Meraukes, and the Irian Jayas are also most often the calmer, friendlier ones, excellent beginner skinks! Note though that babies can be more skittish and flighty, but they do almost always calm down with age.
The other pro with buying from a breeder is that you don't need to know all the signs of possible problems or illnesses when looking for your animal; if there is anything about the animal or its temperament that is less that optimal the breeder will be much more likely to disclose it before you send them your money.
Looks like Dood beat me to the response

Now you get to read some of it twice.
