Its not a tool, its a tool!

Ivy has always been particular about her speech, but about a year ago she started dropping the "s" off of the front words.  Especially words with a consonant next like stop or school.  Her uncle became Uncle Cott instead of Scott.  That kind of thing.  I think it had something to do with her teeth taking forever to come in. (She didn't get the last of her bottom front teeth until December).  Anyways we are constantly reminding her to say her s's.  A couple of weeks ago she asked me where her {s}tool was.   Darin brought it into the bathroom and said "Here is your tool!", purposely leaving the s off just like she does.  

Ivy looked up at him and said " Dad its not a tool, its a tool!"
