Wash baby socks together in a laundry bag so you never lose another one again
How I know it works: This is another one we use IRL, and I no longer get grief from the wife because the kid has on socks that don’t match! Side note: Since little socks get lost so easily, they should make ’em the same color with no stripes! That way if you can only find two — they’ll match! Anyway, until sock manufacturers listen to me, this hack will be help.
