Cossettie is the best place to find innovative baby products that are actually compact, easy to carry around and easy to use. All of the products help keep germs away from little ones. Cossettie's products have been tested by a third party CPSC certified lab and meet all standards including lead, flammability, and small parts. All four of their products will fit nicely amongst all of your essential items in a standard diaper bag with plenty of room to spare. The smallest of their items would be comparable to a snack size candy bar, while the largest will take up as little room as a newborn diaper.
