"Don't Forget the Oatmeal" was published in 1980. Many think of it as one of their favorite books growing up.
Our family remembers it as one that was read to my oldest son very, very often.
The story is pretty simple. A list is worked on for the grocery store and several reminders to "not forget the oatmeal are given". Bert and Ernie go to the store but Cookie Monster somehow is there. Cookie Monsters efforts to find the cookies becomes a focus. Problems follow.
Please forgive me for letting some of the story leak out here. I know this is wrong (never do spoilers in important book reviews) but I am going to leak what happened.
"They forgot the oatmeal!"
Key Characters in this important stor are Bert, Ernie and Cookie Monster. Well worth re-reading. You can listen to it on youtube.
