My kids (3 and 1 and a half) love Sesame Street's Count on Me 123 video. They were a little younger when I first bought it and while the storyline (Ernie finds a 'Furry Arms' room key on the street, returns it to the hotel & starts teaching everyone how to count) went over their heads at first, the catchy tunes, skits & scenes (mainly from the early Sesame Street episodes) soon caught their attention. There's a cohesive plot & everything links well.Now my 3-year-old knows most of the words and even my one-and-a-half can say some numbers - it's a great video, fun to watch even for adults, and I highly recommend it.Learning about Letters is more of a cut-and-paste of other Sesame Street skits & scenes - not that this isn't good, just that it's standard fare. I like that they are taken from the earlier Sesame Street episodes as I prefer the quality then. And my one-and-a-half year old loves the "C is for Cookie" song that I remember from back then!
