ta Leash... he is my "smartest" child but there are so many ways in which brains can be damaged I guess... I was probably just hoping to have something specific to say to my DD so that she remembers not to leave it out.

I think also that genetics palys a large role in whether a person is suseptible to tooth decay. I think the thickness of enamel varies from person to person... those with thin enamel (no matter how careful and hygenic they are) will have more decay. I'm also fairly lucky to have thick enamel... my 2nd child has inherited this... my oldest has my DH's thinner enamel... not sure about my toddler yet...
