Thankfully, the ones that went swimming needed to be replaced anyway, but still, kids need to know these basic rules. I understand how tempting it is to throw things into still water...happens all the time...but please, not toothbrushes, that's just gross.
Speaking of toothbrushes and something gross, a mom had this to share:
"I once said 'Don't brush the cat with my toothbrush!' I could NOT believe the words came out of my mouth!"
Moral of the story? One must explicitly state what exactly toothbrushes are for. Period.
