Just to add my fourpenceworth - my eldest son has ADHD and has also got the same interest in reptiles. Being dyslexic he avoids any opportunity to read, but he WILL read reptile books. We got a leopard gecko (Speckle) when he was 11, however I read everything I could get my hands on as well before we made the decision. The reason we got a LG rather than a beardie was down to size, temperement and feeding requirements. We have a purpose built vivarium together with uv light/spotlight/red bulb/heat mat and temp probe and this means that being on timers he doesnt have to fiddle with the lights and Speckle has the right day/night cycle. I understood that LG were not nocturnal, they were crepuscular, which means they are active at dawn and dusk. We have the vivarium in a dark area of the room, and arrange the lights so that Speckle is active when my son gets home from school and before school. After all it doesnt really matter if the lizard is active during the day, as your child will be at school. Other things to consider, we didnt want a large lizard due to wanting to be able to give them the right size vivarium, a Beardie would need a massive viv to be able to keep them correctly. Also feeding requirements, a LG needs a lot less feeding than a beardie, we have to order our livefood online as its better quality and you get more for your money. When you have postal strikes, keeping a constant supply of food is hard. You will spend a lot of money on decent quality live food with a larger lizard. Could you cope with crickets or locusts escaping? We get silent brown crickets rather than chirpy black ones, but then the first thing you know about them escaping is finding one walking across the work surface in your kitchen. Also you have to be aware that reptiles can carry salmonella, and that you do have to be careful with hygiene. Personally I think 8 is too young, unless you are completely prepared to look after the reptile yourself in every way including handling/cleaningout/removing or feeding live insects when the novelty wears off. Im lucky, my son adores Speckle (they have boy/gecko chats on his duvet

) and has done for the last three years. Hope that helps a bit.
