Not for us
I've watched several episodes in an attempt to determine if the sassy and disrespectful behavior (esp. toward the adults!) was a one-off. Unfortunately, it wasn't. I wouldn't allow my children to watch this at any age, but my husband and I are relatively conservative when it comes to TV viewing and the messages we choose to expose our children to (aged 4 and 5). Super Why, National Geographic, Sesame Street, and Dinosaur Train top our list when looking for TV. Perhaps we parents of little ones are only trying to protect their innocence a little longer... you can't "un-expose" children to ideas (such as sassing your parents, acting self-righteous b/c you're right and someone else is wrong, etc.) As they enter kindergarten and grade school I know that they will experience situations with children and families that make different choices than we do, but hope that by presenting media that is consistent with our rules and the types of behavior that we expect that they will have the strength of character and enough of a fledgling moral compass to negotiate those situations with self-confidence, empathy and good judgement.
