Or she spends time in her "gym". Although I am generally against super-cool toys for kids, as I believe they can play with a paper box with equal joy, I must admit that toys, actually, give kids a lot of pleasure. :)
Yes, I used to be a kid myself, but do not remember being too thrilled about toys as such.
This toy, however, has 10 different colorful pieces hanging above baby's head and she "excersizes" while trying to reach them. And, laughs aloud. Seems that the things have changed since I was young...
