Manage the KIDS?

In all the years I've been doing storytimes, I haven't had nearly the amount of trouble with kids that I've had with the adults that come into storytime with them.  This doesn't mean I don't want them in there, just that I wish they would use some common sense.
Problem #1: Cell phones.  They forget to turn their cell phones off. The cell phone rings during storytime and the adult steps over the children on the way out, talking all the way.  Solution: Start each storytime with the Cell Phone Song:
    I went to the storytime with my mom,
    But she left
    Her cell phone on.
    The cell phone rang
    And she took the call.
    Now we're not allowed back in at all.*
And have the kids pretend to take out their cell phones, turn them off, and put them back in their pockets while glaring meaningfully at the adults.

I also have a sign that used to be posted on the wall (but now that we're in a new library, we can't put anything up until it gets all grungy and lived-in again).  The idea was that if the cell phone rang, the tiger would come out and eat the phone ... and anyone holding it.

These aren't the exact signs - but you get the idea.

Problem #2: Adults talking during storytime, daycare providers/teachers doing their work, or texting.  Rather than shame authority figures in front of their charges, I have a sign I hold up that has the "No cell phones" on one side and the "Please model good listening." on the other.  I may need to flash both.  I do mostly pre-school storytimes, so they can't read and the adults get the message.  If they don't get the message, some day, some day, I may just resort to public shaming.

The best storytime experiences I have had were with groups that had adults who participated.

* This song has more verses that involve restaurants and airlines and gets progressively vitriolic.  I hate cell phones.  Even though I own one, I rarely turn it on. Be in the moment, people!
