Thanks.. I read the care sheets. As soon as I get off work im going to get him some crickets.. ill also post some pics of Dave and maybe that will help yall help me too.Do I need to do "gutloading?" with the crickets I get today? or just feed him and start feeding the crickets for the future? also, he has a "blue" light and a white light in the double light fixture that they got there.. Should I change this? so so many questions.. I will update as I go. Thanks so much for being here. Otherwise Dave would not have a chance.
Yes, yes and yes

Okay when you go the store. You are going to want
Crickets,
Gutload (some fruits and veggies will do, or some pretty store gutload)
A Reptisun UVB light, you want the linear one (the long floruscent strip light) a 5.0 is probably best to start with. Likely be 24 inch, if your current cage isn't that big that's okay turn it diagnoally, it will need a 24x24x48 cage in the end.
A basking light, (a standard light bulb with a reflector) the wattage will take some experimenting. Based on your temps, for now for a baby, maybe just do a 50w, and go from there. You will want a way to see the temps as well, like a temp gun.
You can gutload the crickets for a bit, just let them eat what they will for like an hour then feed them.
Supplements are not every day, but twice a month, calcium if they did not get that is needed every feeding. Calcium without D3.
Then in the coming days, you should aim to get branches, for the cham to use, and live plants.
A mistking system, is going to be very beneficial, as your not going to want to mist the cage all the time.
Post pics of the cage setup, after you get some branches and plants in it, and we can help ya from there. You want to setup microclimates, of different temaptures and humidity.
And congrats on your chameleon, because it is in fact yours. Chameleons require detailed, and exacting care that an 8yr old is not going to be up to do. So they bought you a pet
