Peppa rocks.
Daddy Pig is fantastic, and the whole thing is great. Children are polite to adults and vice versa, there's lots of playing outside and playing together, the speech is clear, and there's those lovely little touches - Daddy Pig carries home the biggest Christmas tree, Mummy Pig says are you sure it will fit in the room, Daddy Pig says I'll make sure it fits...
There's jumping in muddy puddles (hell, I remember doing plenty of that at Peppa's age, long before PP), but only when wellies are being worn.
And what CoffeeMummy said.
