i came to post similar to the op, but my ds gave up naps almost 2 years ago, when he was just 2. we have, until last week, resisted the video/tv as a substitue all this time and have endured absolutely hideous afternoon behavior from him for years. hysterical crying, hitting, slamming doors, and generally falling apart from about 1:30 til his 7:30 bedtime. unfortunately, he is a very "active" book listener, always asking tons of questions, and stories thus do not relax him at all- they hyper-stimulate his mind, which is great, but not for supposed down-time. he gets too moody and cries at sad pats, bounces off the wall at funny parts, etc. when he is too tired. music, too, makes him move all around and hypes him up, which just makes for a worse crash later on. i recently had a baby, and last week we moved to a new house. ds has had so much change in his life,and his afternoon behavior worsened. so, for the very first time, we tried a video one afternoon after resisting for so long. After 45 minutes of watching, he had an amazingly happy afternoon. we have done it several times since, and with the same results. obviously, since i waited 2 years o give in, this is not my preference or first choice, but so far, if it is the first activity that seems to relax him- regardless of what the research suggests, i'm going to allow it and see how it goes.
