Sesame Street is taking on another tough issue.

The children's TV series is expanding its "Little Children, Big Challenges" series by introducing Alex, a Muppet whose father is in jail.

Alex is part of Sesame Workshop's online tool kit aimed to help kids understand and cope with parental incarceration.

It's also a tool to help caregivers talk about the subject with children.

Some find the character a bit odd, but one in 28 American children reportedly have a parent in prison.

Sesame Street has used Muppets to tackle other tough issues like divorce, hunger and military deployment.

Do you think it's a great idea or do you find it inappropriate?
