When Hagatha puts down her stethoscope-like device on the table it isn't present in the shot over her shoulder of Samantha and Endora.
Before Maurice appears, Clara has her gloves on and still does after he appears. On the distant shot the last we see her gloves on is when Tabitha touches the glove of one of Clara's hands. It then goes to close up shots of Clara, Endora, then Maurice and Samantha. When it goes back to a distant shot and Maurice walks over to Clara to greet her, she now has the gloves off her hands and is holding them. We never see her take them off.
When Tabitha's powers are tested, her mother and aunts plan on taking Tabitha to a Magic School against Samantha and Darrin's wishes. When they make Samantha, Aunt Clara and Darrin's feet stick to the floor, Samantha calls for her father to help. Just before he arrives, you see Samantha's right foot move. When he does arrive and ask her; "Trouble Samantha?" Samantha is clearly moving a bit, but Darrin and Aunt Clara are not.
In the final scene, when Maurice is holding Tabitha, he shushes Samantha, telling her that he had just gotten Tabitha to fall asleep. In the next view of the toddler and her grandfather, however, Tabitha's eyes are wide open before she quickly closes them again.
