It is that fact they gave her something she isnt suppose to have. lol We use to do this for our kid. When she was a baby and we needed her to quiet down but no matter what we did it didn't work we would give her my husbands wallet or our keys or sometimes my necklace. Shut her right up lol she be so amazed she gets to play with something she normally isnt allowed to play with she forgets why she is crying.
Boom
