1. At a restaurant with TVs, we've observed our child go from laughing and socially engaged, to completed zoned out and unaware of people in mere seconds, just because the television appeared in his field of view. :-(
2. At less than three months of age, he had a fit when pulled away from the television, under the watch of in-laws.
3. Both parents have iPhones, Macbooks, and have a tendency to flop in front of the TV (Roku, Hulu, Daily Show) in the evening. Our no screen time policy prevents us from gazing into our own screens without paying attention to the needs of our son.
4. Finally, most advertising is obnoxious and has no place in my home. Why expose our infant to it? He'll have the rest of his life to be accosted by ads.
