My nephew is turning 7 next week, day after Liliians birthday He loves Legos, specifically the ninjago ones. He also has game things, like play station hand held and all that so he likes new games.
My nephews are around that age and lego's are always good. Also, nerf guns, Wii/DS games (like Skylander stuff), my 6 year old nephew loves Imaginex and anything Marvel superhero's (like action figures with cars)...
