Some may poo-poo the idea, but my grandson was two months premature and weighed 3.1 pounds when born. He still started talking at about a year, and full sentences by two. He is now 5 and can carry on a conversation with an adult.
My kids refused to have a TV, and when they brought him over, we turned ours off, too. His “special” treat on his 3rd birthday was to watch his FIRST video. His father read to him out of the Bible and read the whole thing to him before he turned one.
Glad to hear a positive result, such is not uncommon, less to no pop-culture and interlocking corporate media influence is healthy for growing children; keep up the good work.
