Charlie has the heaviest footfall... when he runs around, it sounds like a monster is stomping his feet and getting ready to storm a castle! Maybe even 100 of them at once... it's like a stampede of cattle.
He may or may not have gotten that from me... oops!
When your LO runs around, does it sound like 100 monsters stomping their feet at once? What about you and your SO... do you guys also have a heavy footfall?
