We're pretty lax about this, too. From the start, my and my husband's philosophy has been, as long as it's not a safety issue (rocks she'd choke on, cords she'd shock herself with), it is up to our (currently 11-month-old) daughter what she puts in her mouth. Dog bone? I wouldn't do it, but she's free to. Cat toy? Sure. Playdate's shoe? No problem. And aside from medicine when she needs it, the same goes for ingestibles. We give her a selection of healthy food options, and she decides what she eats and what she doesn't. I'm all about washing my hands after using the restroom or changing a diaper. But that about covers it, unless I've got something visibly dirty on my hands.
