Let's see...
I have 3 hair brushes, DH has 1.
We each have a regular toothbrush, plus we each have a brush for the sonicare electric toothbrush. I think we each also have a "spare" toothbrush that I pack for our summer travel, so that's 6 toothbrushes.
Of course, we have the obligatory toilet brush.
Oh yeah, and the baby's hairbrush, plus a toothbrush for her.
So that brings us up to 13 brushes of one sort or another.
