John, babies know this. When yours is a bit older, maybe this September, go sit outside on the lawn, hold the baby under his arms and try to put his feet on the grass (as if to stand him up). Watch what he does! (I'm assuming WC is a boy...)
"But for many people, the joy of feeling the cool grass underfoot may outweigh one of its consequences, bromhidrosis, known colloquially as stinky feet, which is caused by bacteria that thrive in moist places — and thus is a risk of putting wet feet back into shoes and free spirits under wraps again."
