Adam was the name of Darrin and Samantha's second child, but only son. It was originally believed Adam was a mortal but was later shown (in the final season) that Adam had magic of his own. While Adam was a warlock on "Bewitched", he was a mortal on the spin-off series "Tabitha".
The births of Adam and Tabitha were a result of Elizabeth Montgomery being pregnant while filming episodes of the show.
Answer: Elizabeth Montgomery
Elizabeth Montgomery (1933-1995) played Samantha for the entire length of this excellent series, appearing in a total of 254 episodes in all. During this time, we see her character Samantha going from a young newly married woman, who happens to be a witch married to the mortal Darrin, right through to the birth of two of the couple's children. Her main role in the series is acting as peacemaker between her irascible husband and her equally irascible mother as the two constantly butt horns, with disastrous consequences for Darrin when he raises the ire of that fiery older woman. Samantha, by the use of her magical twitching nose, has to fly to his rescue with the use of counter spells and solutions just in time to save the day.
Answer: Peter Lawford
Peter Lawford guest starred as Harrison Woolott, a love interest for cousin Serena in the episode titled, "Serena's Richcraft". Mr. Lawford was married to Patricia Kennedy, the fourth daughter of Joseph and Rose Kennedy, from 1954-1966.
Answer: Elizabeth Montgomery
Elizabeth Montgomery, born April 15, 1933, played the role of everyone's favorite witch, Samantha Stephens, for eight seasons. Ms. Montgomery went on to star in many television movies. Unfortunately, the beautiful actress passed away in 1995 of cancer.
Answer: Because she was married to a mortal
The witches council disapproved of Sam's marriage to a mortal, so they told her she had to divorce Darrin or "suffer the consequences".

"Bewitched" aired on September 17, 1964. The first episode was "I, Darrin, Take This Witch, Samantha".

Answer: "Nobody's Perfect"
"Nobody's Perfect" was the first episode of season 3. It was also the first episode in colour and the first episode where the Murphy twins played Tabitha. Darrin found out that Tabitha was a witch in "The Moment of Truth", which is the second episode of the season.
Answer: Gladys Kravitz
The Stephens' nosy neighbor Gladys Kravitz was played by two different actresses. She was played by Alice Pearce for the first two seasons and by Sandra Gould for the rest of the series. Gladys was married to Abner, who didn't believe his wife's stories about the strange things surrounding Samantha.
Louise Tate and Frank Stephens were also played by multiple actors. (This excludes Tabitha and Adam, since they were young, and it's common to have characters that young played by multiple people, usually twins, due to child labor laws.)
Answer: Dick Sargent
Dick York (1928-1992) played the role of Darrin for the first 156 episodes of "Bewitched". In the early part of his career, he had injured his back badly during the making of a movie. For the rest of his life this caused his enormous pain, but he continued acting in spite of it all. He was in such agony during the making of "Bewitched" that in the latter part of his time on the series, he often had to be filmed lying in bed or on a couch. He finally couldn't go on any longer, and, with the greatest reluctance, had to give up his role. His character was not written out of the series but replaced by another actor instead. Dick York spent the greater part of the rest of his life bedridden from this injury, only well enough to occasionally appear in other television series in guest star roles.
Answer: Jack Cassidy
Jack Cassidy guest starred as Rance Butler in the episode titled, "Samantha Goes South for a Spell". Jack's famous son is David Cassidy from the "Partridge Family".
Answer: Dick York
Dick York, born September 4, 1928, played the part of Darrin Stephens, Samantha's mortal husband, from 1964-1969. He left the popular role due to a chronic back ailment. He passed away in 1992 from emphysema.

Answer: Makes him feel pregnant
Darrin keeps ordering Sam to do things around the house. Endora makes him feel pregnant so he knows exactly how Sam is feeling.
Answer: Mary Jane
Sam loses her powers, which is probably a good thing, because otherwise Mary might have ended up as a doormat! Mary Jane was played by actress Mala Powers. Mala also played Mona on the TV series "Hazel", which aired in 1965 and 66.
Endora, Hagatha and Enchantra come to visit and test Tabitha's powers.
Answer: A centaur or a unicorn
"I'd like to leave a little play thing for the baby, I thought a centaur might be nice! If you don't want a centaur then I can always give her a unicorn instead." - Serena
In all seven babies played Tabitha. The first was Cynthia Black who appeared in just one episode - 'And Then There Were Three.' Cynthia was then replaced by slightly older twins Heidi and Laura Gentry. The Gentry twins were then replaced by Julie and Tamar Young who appeared in the role for the remainder of the second season. Starting with the third the role was played by Erin and Diane Murphy.
There were also two adult Tabithas - Liberty Williams and Lisa Hartman - who appeared in two separate spin-offs. The final Tabitha was Cindy Eilbacher who voiced the young witch in an animated feature 'Tabitha and Adam and the Clown Family'
Elizabeth Montgomery played Samantha in every episode. Montgomery played other roles sometimes besides Samantha in "Bewitched".
Answer: Dodo birds
In the episode 'Allergic to Macedonian Dodo Birds', Endora loses her powers because she has come in contact with a Macedonian dodo bird. It is then discovered that Endora is allergic to dodo birds.
In total, there have been 9 Tabithas over the years, but only 6 of them were twins. Heidi & Laura Gentry were the first set of twins. They played Tabitha in episode 54. Tamar & Julie Young played Tabitha from episode 55 to 74. Erin and Diane Murphy continued to play Tabitha from episode 75, until the show ended. As well as the Gentry twins, in " And Something Makes Three", Cynthia Black also played Tabitha. The eighth Tabitha was played by Liberty Williams, in a spin off show called 'Tabatha' in 1976. This show never took off. The final Tabitha was played by Lisa Hartman, in another spin off show called 'Tabitha' in 1977. This show was picked up for 12 episodes.
Aunt Clara accidentally created a carbon-copy of the poor kid in the third season episode, 'Accidental Twins'.
