Peep is my daughter's favorite show, hands down. She is now 3 1/2 and has been watching it for over a year. It is the first show she asks for in the morning and the first one she wants after nap/rest time.
Her dad and I have seen every episode that has played on TLC (more than twenty times each), and we keep at least 10 or so on TIVO. We often find ourselves quoting Quack lines throughout the day.
We even used craft clay to make (and bake) our own Peep, Chirp, and Quack. Now she's asking if we can make the rest (Newton, the Ants, Squeak, Madame Hoot, etc.) It is a wonderful program, and we cannot wait to see new episodes!
Oh, and today she has asked me for some string, tape, a straw and two empty plastic bottles to make her own "experiment".
