This isn't to say that I follow Marie's rules to a T. My folding style is a bit off from the way she does it, but it works generally the same and is easier for my daughter – who now watches me fold her clothes and occasionally offers to help – to replicate.
I don't bother folding toddler underwear or lining up socks, but I do have designated boxes for them in her drawers. Same goes for her accessories. Her top drawer is filled with bins – one for bows, one for headbands, another for sunglasses, and still one more for mittens and gloves.
