If reaching for your diaper bag is a hernia-inducing experience, it may be time to look at smaller options that limit the number of products you can carry with you on your next outing. Fashion darling, and Fab favorite Jenni Kayne found herself in such a situation when she was preparing for a quick walk with her newborn son, Tanner, late last year. The designer got to work creating a bag large enough to fit the necessities but small enough to fit under her stroller, resulting in the Jenni Kayne Mommy Bag. Kayne has teamed up with drugstore.com to fill the bag with full- and deluxe-sized samples of some of our favorite eco-friendly products for mamas and tots, including California Baby, Burt's Bees, Seventh Generation Diapers, and Avent bottles. The bag is free with any $75 purchase on the site, so now may be the perfect time to restock your changing table with all of the necessities.
