We requested blocks, she loves stacking the two that we have. And she has loved playing with the ones at her aunt's house.
We're just getting her two gifts, stacking cups and an small standing activity center. I think I spent under $40 on her all together.
If your daughter isn't walking yet, you could always get her a little bike push toy or walking aid. Our 11 month old loves the little scooter we got her, the walker they have at daycare, and the one her aunt has. She just walks all over the place with those. But then she also grabs chairs, step stools, rubbermaid bins, and laundry baskets and pushes those around too.
