Goodnites

Goodnites are the brand of bedwetters' diapers by Kimberly-Clark. The father was reminded to take a bag of them with him and the kids as Lilly was still a bedwetter as of those events in the movie. It was shown prominently in the movie three times; a prime example of cinematic product placement. After the scenes in Yellowstone Park, the Goodnites were never seen again.
