What they don't tell you about parenting

There is one item that parents are unaware of the vast need for when having children.  It is something a child needs in a majority of their things and something that brings loud complaints when they fail - batteries. If you haven't taken stock out in it yet, you might want to think about it. Batteries are the one thing I always buy extra of because the time will inevitably come when I hear, "Mooooooooom, these batteries don't work."  It happens all the time.

I know about the huge expense for diapers and formula but nobody ever told me a lot of batteries were another required expense of having children.
