I'm a huge fan of Sassy Toys for babies. and their bath toys are no exception. These cups not only have the benefit of being fun in the bath, but they're also BPA free, so there's no worries when your child inevitably puts them in their mouth.
According to the Soft Landing Blog, Sassy has all kinds of BPA free bath toys, but the cups are definitely my favorite. Like most toy cups, these stack up and nest inside each other, as well have numbers and corresponding holes in the bottom.
