When both the Tramp and the Kid are chased by the policeman, the Kid loses his cap which falls to the ground in the yard before he could enter in his home. Still, when he is seen inside, he has got his cap back upon his head.
When the Woman is giving toys to the children on the street, she sits down on the curb and a woman hands her a baby. When she takes the baby, she sets the last two toys, a dog and a ball, next to her on the curb and the ball rolls off the curb a couple of feet. A few shots later, when she meets John, she picks up the toys and gives them to him, but the ball is back in position next to her on the curb.
After John has made pancakes and the Tramp gets out of bed, a kettle can be seen on the corner of the table. After the Tramp has put a chair next to it and goes to sit on it, in the next close-up shot of them on the table, the kettle is missing.
While baby John is in a hammock, the Tramp is cutting sheets for diapers and folding them over his chair which is right next to him. In all subsequent shots of him and the chair, the folded sheets are gone again.
When the Tramp finds the baby while sitting in the sidewalk, he leaves his stick by his right side. After the shot of the baby's mother's letter, there is no stick by Tramp's side, and after another shot, it appears again and in a different position.
On the rooftop, after the Tramp chases the two welfare workers who have captured and tormented John, the scene ends with the Tramp and one of the workers fighting on the back of the workers' pickup truck. After kicking the second welfare man off the back of the pickup, the Tramp makes a 'nonsensical' wave-good-bye as he and John ride off to momentary safety. In reality Chaplin (also the director) is waving 'CUT' to cameraman Rollie Totheroh.
