I don't mean to be a huge jerk, but I will note the age of the author's kids--4 and 18 months, was it? She may be a teacher, but her own children are not (probably-- I imagine the 4yo would be encouraged to stop if he/she did read!) of reading age yet and she doesn't have the understanding of what it is to have one's own child reader and how this process can evolve in the home.
I wondered this too so obviously you're not a jerk
I claim the jerk prize, for having wondered whether the underlying motivation for the article was to allow the author, who perhaps always assumed her own children would be early readers, to convince herself that it's actually a good thing her 4yo isn't reading yet. Of course this may be entirely wrong in several different ways.
