any moms collect teeth?

Kristy
Husband thinks I'm a weirdo cause I kept my daughter's umbilical cord stump, and want to make a keepsake necklace with one of her first teeth. 
Now I know the jewelry part maybe strange, but isn't it the norm to save your child's baby teeth?? I know my mom had ours and locks of our first haircuts. & I've seen boxes that come w baby books for those specific milestones.
