Rubber band pant legs over sockless baby feet
Shirky McLazy's little sock hack:
We went out and the baby lost his socks. I pulled his pants over his feet and rubber-banded the ends closed. Tada! Warm feet!
Speaking of lost baby socks, the only thing that ever kept socks on my kids' feet were Robeez booties. Not really necessary for the non-walker, but they sure are cute. Just got a note from their publicity person that (for a limited time!) they're giving away free matching socks with selected booties. Good opportunity to replace the ones you've lost!
