She has been chewing up all her hallow plastic toys.

Two of those toys I had since I first got her (oh, the memories

) and the ambulance one my mom bought me b/c I'm on the Squad! It even makes a siren noise, and she ruined it. Why is she tearing up these toys? Now I have to buy her the hard as heck toys and stay away from the hallow squeaky ones.

Does anyone else's baby do this?
