I have a seven year old girl and a five year old boy. They are both very into science so--- we are buying various habitats for bugs, a volcano, and some Young Scientist kits (toy r us), etc. We are also buying cactus (cacti) b/c the boy is nuts over them! Go figure The rest of my list is pretty normal.
When my boys were that age they loved any kind of cool action figures. Back then Power Rangers were huge (and impossible to find). They also loved Batman stuff and GI Joe stuff. My younger son also loved to do Legos, but the older one didn't so I guess that is based on the kid. Boys were always easy to buy for...cars, actions figures, legos, transformers, etc. etc.
Now they are teenagers and I have a 7 yo girl. IMO, she is harder. She likes girly stuff, but she doesn't have a particular thing she likes. I LOVE buying clothes for her, though!
has figured out my username! ! He is 9 and getting video games for his x-box and computer, an action figure (large), tons of books because he is an avid reader, moon sand, something like a ball pogo stick called a zoingo boingo (I think?), a chair for his room, new shoes in a camoflaug print and stocking stuffers. Maybe a gift card to the pizza parlor.
