DIY baby clothes dividers. Bought the clothes dividers from Dollarama (they were actually black chalkboard door hangers $1.25 each). Painted them. Titled them. Glue gunned the store bought wood animals from Michaels Arts & Crafts $0.89 each. Et Voila!
I separated my girl's clothes with shower curtain hooks but even if you use a different colored hanger or a piece of masking tape it helps to not miss your child fitting into an outfit - but don't just go by the size on the clothes.
