DD3 (almost 2yo) makes a slapping sound when she walks. "Slap slap slap slap" and we know she's on the move. Her tread is also a bit heavy and we can hear her when she gets out of bed on the first floor.
I've always found it kind of cute but it's starting to worry me slightly.... I don't remember her sisters making this much noise. Should I get it checked? Or wait a couple of months more? (At what age is the next check? 2 or 2.5yo?)
