This thing is SO cool! It's made out of silicon and has little bristles on each side. It's small enough for Salem to hold and all she does is chew on it and she can brush her own teeth! How rad is that? I just have to rinse it off each time she uses it. It feels good on her teething gums, too! You can find it on amazon or just google "Baby Buddy Toothbrush." This is a genius invention, my opinion.
