My 5yr old great-nephew had to have all his teeth capped too, but that was a year or so ago. His WAS bottle related though. My niece was young and just apparently didn't know not to put him to bed with a bottle of juice. She's been much more careful with her younger daughter. Live and learn I guess.
Silly big kids though. They drove up and the baby could hardly sit up and told me they were taking him to the park because he did so good. I asked my DIL if she felt like going to the park after she woke up from a C Section. They looked at each other and brought him in the house.
