So many comments seem to gloss over the fact that kids are very different and what works for you is cool and all, but not necessarily going to work for others.
Going with no TV is noble, good for you. But going from heavy use to no use is not necessarily the reason your child is doing so good. There is a balance is that balance is unique to each child.
From the article: "Watching television or videos is discouraged for babies younger than 2 because studies suggest it could harm their development, a pediatricians’ group said Tuesday."
But you say: "There is a balance is that balance is unique to each child."
How do you know that there "is a balance unique to each child"? Do you have studies to backup your assertion similar to those cited in the article?
