DD is nearly 8 and she loves Monster High as well.
She's pretty easy to buy for, honestly. She still sort of likes the princesses, but she doesn't really want her friends to know. She loves Littlest Pet Shop, Zoobles, Legos. Anything little that have a ton of pieces. She also loves American Girl dolls and REALLY wants another one this year (which isn't even remotely in the budget, and completely my fault since I wanted to buy her her first one last Christmas, and my bf told me I was just reliving my childhood and she would never know about them if I didn't start this mess)
From Santa, she's asking for an Easy Bake Oven, another Fidgit friend and one of their small friends and that diary that is voice controlled I think. I really hate all of the things she's asked for from Santa, though the diary is tolerable.
