For many new mothers, the experience of early parenthood means having a smartphone in one hand and a baby in the other. Common tasks include: Searching Google Images for horrifying rashes, watching instructional YouTube videos on swaddling, acting as their baby's own personal paparazza, texting photos to grandparents, and, of course, shopping online. Among other parenting pitfalls, new mothers must also now try to avoid giant giraffes, colorful tunnels, and other impulse buys they might regret in the morning. "Moms send us stories all the time of nursing her baby at 3 a.m., realizing she's almost out of diapers or some other essential, placing an order with us through our app, and having the package show up at her door later that day," said Michal Geller, a senior vice president of marketing and business development for Diapers.com, one entity in the baby-industrial complex — the diaper market alone is expected to reach $52 billion globally by 2017."Same-day delivery is a game-changer for busy moms."
