Here is something cute I found while trolling through YouTube the other day. I posted it here, thinking that other parents might like to sit their preschooler on their knee and let them watch this three-minute alphabet song. It was uploaded to YouTube by 1Ronledson, who according to his profile is 71 years old. The Zoo Animal ABC lists that it has had 4 1/2 million hits.
Play this song several times, then encourage your preschooler to sing along. There are many other alphabet songs for free on YouTube. If you find another that you think is especially cute, post the link in the comments section! This could be a page that you come back to again and again. Happy singing!
