At the beginning of the movie Isabelle (Julia) is searching for Ben when she gives up and decides to make the kids lunch and goes to get peanut butter from the cupboard and finds ben in there, to have him shove a container of peanut butter in her face. Later when she gets to work her assistant says, "You have a fruit loop in your hair," and he picks it out. Why is there a fruit loop in her hair?

If you own the movie, you will see a commercial for the Stepmom CD, and if you watch closely, you see a scene of Isabelle in the kitchen and going for the cupboard and Ben throws a bowl of fruit loops at Isabelle. Obviously, they decided to re shoot the breakfast scene but forgot to change the fruitloop in the hair scene.
