Don't feel too bad for putting your child in front of the TV - as it's claimed that Sesame Street is just as educational as preschool.
A new study has found the show has lasting educational benefits for the millions of children that watch it - with strongest effects for boys, children in disadvantaged areas, and African Americans in the US.
Researchers believe the effects probably come from the show's focus on reading and maths, that helps to prepare children for school.
They have found the education from the show is as powerful as the lessons they learn in preschool.
