Who invents these things?

I found a great (and really odd) invention today.  So today I was at the mall and my newly potty trained daughter is afraid of public toilets.  She has only used them one other time, but it was bad.  She thought it was fun that they had a toilet her size but then as she went to sit down it flushed on her.  Well she was scared as any 2 year old would be, but I assured her it was okay . So she sat down only to fall into the toilet (YUCK).  Well, we made it through that but today she did not want to use the toilet at the mall.  It just kept flushing any time she moved near it.  I was trying to block the sensor but it's a little hard when I still have to help her also, especially since she was afraid of falling in.  So when I got home today I searched "how to stop automatic toilets from flushing" and I found Flush Stoppers. They are a little $3 thing that goes over the sensor so I can tend to my child and she knows it won't flush. It comes in its own little carrying case. I am excited to try one. Yes, I did order one. (it was $2.99 with free shipping) I may have just wasted $3 , but it seems like it might work.  I'll let you know!
