Peppa Pig is so harmless and sweet.
How is she a brat exactly?!
Charlie and Lola is outright hilarious - so what if my nearly 4 year old DD occasionally now quips "I am NOT sleepy and I will NOT go to bed"! (she is, and then does, by the way)...they will always copy and cite stuff back, but the point is she knows it's just a film and that it's meant to be funny, so hasn't changed her behaviour in the slightest. Plus, as others have said, at least there are the little moral tales hidden within, as well.
What I really loathe are Waybuloos and Rasta-effing-mouse, who do not speak properly, or in the case of Waybuloos not at all...DD imitating dialogue/expressions or general English which is incomplete or incorrect, really pisses me off - hard enough to get kids speaking good English without crap that encourages the opposite.
Breathe.
