If you have a small child in a car seat, you have probably found yourself wishing there was a way to safely store things within their reach. One thing I regret is buying one without good, solid cup holders. At least having a little bag will provide a place to slip a sippy cup within reach. These dual bags can also hold books, toys and snacks. Best of all, they can easily be removed for washing. Cargo-style pockets allow for expandable space.
