Query: so glad I bought this

I bought this dvd set for my son around his second birthday. He already knew how to identify numbers and letters before I purchased this.So he wasn't interested in those dvd's.He leared his colors and shapes in a coulple weeks.Now at 27 months he can identify almost all the sight words in vol. 1 by him self. He's about ready for vol.2. Not all kids like this, I put it on during a couple playdates. My son was the only kid watching it.The other 2 year olds wanted toy story or nemo. So glad I bought this.
