5 Kids Script

I read an interesting thing on IMDb, about an original script having 5 kids and one dying in the sprinkler scene. I couldn't find anything about that anywhere else online. I wonder if that kid would have been one of the main characters we know, probably not. Or possibly some other character and if they would have been a boy or girl along with being some random kid or another family member to either families. Of all the adventure those characters faced, the sprinklers were what killed him. But, if a character died in this movie it would make the movie less of a comedy and more serious. I think the script was written well, but can anybody else find anything about this?
