content: My youngest watches 1 episode a day of sesame street. At 2 1/2 years old she speaks full sentences and can articulate her wants and needs, count to 20 and recites the alphabet while also recognizing about 10 actual letters when just shown to her individually. It's not all thanks to the show, but reinforcement from us, daycare and good TV helps rounds out her learning. Sesame Street is one of the best things out there if you absolutely need to stick your kid(s) in front of the TV for a little bit to cook/clean/use the bathroom.
