Surviving quadruplets "brushing their teeth"

Surviving quadruplets "brushing their teeth". Our quads were born at 26 weeks and 2 days. Our daughter, Carrie, passed away at five weeks old. Our three surviving quadruplets are almost 18 months old. Mom brushes our teeth and then we practice... and clearly they are not done.
*no toddlers were harmed in the making of this video, however, plaque has been destroyed. Ha!
