DS (8 mo) likes anything that's not a baby toy. So, as long as he won't hurt himself and as long as I don't care if it gets drooled on or dropped, he can have it. He loves my keys, wooden spoons, the pasta strainer, the arm to our rocking chair, an old toothbrush (well, not old, but he took it over so I had to get a new one). He really, really loves my phone, but I'm not ready for him to destroy it so I tend to keep it away from him.
whole raw veggies - just be smart about choking hazards of course.
get a washcloth wet and then stick it in the freezer...goodtimes!
