Shake 'em socks
Your baby is constantly growing. Try this great new invention for rattle socks.
Rattle socks are great to have for their developmental qualities, but your baby is going to outgrow them pretty quickly.
Using small soft toys, cut a small slit in the side and push in one or two bells. Stitch the side up and, using safety pins, attach the rattles to the pair of socks that fits your baby. When he outgrows these socks, simply transfer the rattles to the next pair.
