I'm not sure where Madison got this Piggy Bank (I think it was one of Trinity's birthday presents), but she is diligently filling it with money. Nothing silver (or copper) is safe, and I have caught her several times digging the loose change out my purse.
She is currently saving for the Polly Princess Carriage (with Prince Eric included). Although I'm sure I'll end up getting it for her eventually, I am encouraging her "saving" behavior. She's learning the value of a dollar, unlike her wee-bit spoiled older sister who wants every toy she sees on TV.
