Plot hole: It's amazing that the two Chapman women weren't caught at "Rock for Daddy Day Care". One of them unzips a guy's dog costume in the middle of the path with everyone walking by. A little kid actually stares right at her when she does this. Also when Jenny puts the cockroaches in the salad, the people who were waiting in line for food would definitely have seen her. There are many more parts like this.
Suggested correction: And yet this kind of thing happens in real life too. Where somebody goes around causing a ruckus in a crowd, people around see them, but they say absolutely nothing and let them get away with it. It's called the "Bystander Effect," where people don't want trouble, so they assume somebody else around will do something. The encouragement of "See something, say something" comes from this exact thing. If it happens in real life, there's no reason it can't happen in the movie.
Continuity mistake: The inspector is giving a puppet show. At the start of the show, Brenda is seated at the far right. In the last shot, she is now at the far left, though no one has gotten up during the scene.
Audio problem: At the end of the film, when Ms. Harridan is working as a police officer, the whistle drops from her mouth in astonishment when she sees that her former employee Jenny now works for Daddy Day Care. She never puts it back into her mouth, but then when she tries to stop a green minivan from going to Daddy Day Care we hear the sound of her whistle.
Continuity mistake: When Charlie reads "Green Eggs and Ham" to the kids, Becca is shown without a book and is just listening to Charlie, but in the next shot of her she is reading along in her own book.
Other mistake: Many of the lines that Charlie reads from "Green Eggs and Ham" don't match the actual book. For instance, he says "Would you like to eat them here or there?" when in the book it states "Would you like them here or there"?. Also in the next line he reads "I would not like them anywhere" when it really says "I would not like them here or there, I would not like them anywhere".
Continuity mistake: When Charlie and Ben are drawing pictures at the table, there is a green cup at the center of the table. But at the end of this scene the cup is at the far side of the table.
Factual error: There's a mistake when Charlie is reading "Green Eggs and Ham" to the kids. Right after reading "I do not like them here or there, I do not like them anywhere.", he shows them a picture of that character holding a fist and says "He was gonna punch Sam I am". The picture he showed them is not on the same page as that line in the book "Green Eggs and Ham". It only comes in about ten pages later.
Visible crew/equipment: In the Cotton Candy Puffs scene, there are two shots of a TV in the corner of the room, and in each of them you can see the cameraman's reflection.
Visible crew/equipment: Early in the film, when the little kid Ben is brushing his teeth, equipment is visible in the glass behind him.
Continuity mistake: When the men are deciding which two kids to fire, one of Phil's hands is on his knee and the other is on his side. Then he says "How about Becca and Jamie?", and then his hands are both in between his legs.
Continuity mistake: When trying to get the house to pass inspection, Phil adds child gates to both ends of the stairway, doorways, etc. However, later shots of the main staircase show that there are no such gates installed.
Continuity mistake: Phil throws his papers on the ground yelling in pain, but later he is shown lying down groaning and the papers have stacked themselves up.
Continuity mistake: When Charlie pulls up in front of Chatman Academy for the orientation, Ben's shirt is untucked. Charlie kisses his wife and she picks Ben up. Ben's shirt is suddenly tucked in.
Continuity mistake: In the scene when Charlie and Kim first go to the orientation after Kim asks the SAT question and turns slowly around with a pleased look on the face it then shows her turning again after Charlie's two way goes off.
Continuity mistake: At the start, when Ben asks his dad "Can you stay here?", his hand goes from being on the bare table to on the paper to on the bare table again.
Continuity mistake: When Phil is being chased by the bees, we see that the kids and Charlie are watching through the window. They switch position between shots.
Continuity mistake: On the first day of Daddy Day Care, the kids are all shown sitting on the stairs listening to Charlie's speech. Flash is sitting in the front row at a fair distance from Becca. Then Charlie hands out the mission statements, and Flash is suddenly right next to Becca. There would have been no time for him to move closer.
Continuity mistake: During the scene where Jeff Garlin is poking the beehive, notice that about 5 seconds later it's gone when Marvin's spraying him.
Continuity mistake: After the day care centre opens, Phil is playing/singing Rhinestone Cowboy on the guitar. The girl in the polka-dot dress and the boy in the red "1985" T-shirt change positions between shots. She is behind him in the front shot, and in front of him in the rear shot.
