"The chart above is data provided exclusively to AdAgeStat from an annual survey from Parenting Group, the publisher of Parenting, Babytalk and Parenting.com, and the BlogHer network. The generational breakdown is striking. Across the board, younger moms are passing technology along to their kids at an early age. This might not seem too surprising, given the Gen-Y embrace of technology. But when you consider that many of the youngest Gen-X moms are still having their first kids, whereas many millennials are putting off having kids, the adoption rates of technology start to blur.
Digging deeper into the data we see that the percent of moms who haven't let their children use a smartphone corresponds roughly to the percent of moms who don't have a smartphone themselves. We suspect that moms who haven't let their 2-year-olds use a smartphone likely got a smartphone when their kids were already older than that. Crazy, eh? Looking at stats for more-established technologies would seem to confirm that. The Gen-Xers and Boomer moms -- who are more likely to have older kids -- do show a higher overall rate of having passed the laptop or non-smartphone to their children of all ages."
