A quick grain of salt on methodologies. We're always a little wary of in-group surveys like this, but this study was a mix of BabyCenter users and general population. Here's its fine print: "The study captured the opinions and behaviors of moms and members of the general population through an ethnography of 23 moms with smartphones that included over 1,000 text logs, 200 video entries and 32 hours of in-home interviews, followed by an intensive series of six surveys of 5,000 mobile moms and the general population, including a survey conducted with Socratic Technologies comparing moms recruited from the BabyCenter 21st Century Mom Panel with nearly 1,000 members of the Socratic Forum."
