Thanks everyone. I really love this board because I can talk about things so openly and get interesting responses. She was able to do 36-48 puzzles at two, but had limited interest. She never touches blocks but because her baby sister stacked some one day, she started stacking and it was taller than she was, but it just isn't her thing and hasn't touched them since. She use to love dinosaurs, but is less intersted lately and I am wondering if she is getting the idea that girls do some things and boys do some things. That is why I try hard to model certain things and show her books where women are doctors (all her doctors are female) etc.
I remember having a math professor in college who told me I could go "all the way" with math and that an English major was for people "who weren't good at math" but it just didn't fulfill me the same way that the humanities did. I did buy her some K'nex with eyes and faces and we have been making them together (she mostly watches me so far) and she likes to use them to act out stories. Maybe it is a girl thing: she is interested in what they might say or express and not just not into building for the sake of building and honestly, I can relate. I'm the same way! I think she actually did better on block design, maybe 96th? It is just funny that I somehow see this as her area of weakness. YIKES I better get some perspective!
Some kids just don't 'build', it's just who they are. That said I would probably see if there isn't a certain type of toy that might catch her interest. The favorites in our house for both kids are Tinker Toys, the new Trio blocks (they love these) and Legos. My DD doesn't have anywhere near the interest in Legos that her brother has so doubt she'd play with them much if he wasn't. Tinker Toys are great though and let them just have a blast while actually building. The Trio blocks snap together with ease and they enjoy making fun things out of them or even just making the examples - DS loves to follow instructions for building things.
