JACKIE'S BABY, ANDY HARRIS

It took four boys to handle the role of Andy Harris, the baby of Roseanne Conner's sister Jackie. For the first three seasons, the honor went to fraternal twins Kent and Garrett Hazen of Orange County, Calif.—even though Kent did not make a terrific first impression. "He barfed on Roseanne," says mom Karen, 39, a nurse. No longer in showbiz, the Hazens, now 6 (dad Craig, 40, is a college professor), earned enough to pay for private school for them and sisters Maggie,11, and Donika, 8. Tyler and Trevor Battaglia, 7, took over the part of Andy just before the series ended. "Their favorite things to do are playing basketball and going on auditions," says their mother, Dorit, 39, a teacher. The identical twins (their father, Frank, 40, is also a teacher) are celebrities in their hometown of Lemoore, Calif. "People are still asking, 'Were you the kids on Roseannf?' " Dorit marvels. "The boys eat it up."
"I could just tell she loved my boys," says Karen Hazen of TV mom Laurie Metcalf (above, with Garrett in 1995). And the boys didn't mind performing. "When they were tiny babies, Kent liked it more, and as they got older Garrett enjoyed it more," says Hazen. "He did a speaking part. He got to say, 'Grandma's crazy.' That was a highlight. I look at the show as such a blessing."
UNCLE JESSE'S TWINS, NICKY AND ALEX KATSOPOLIS

"They were outgoing, funny, and we all loved them," says TV mom Lori Loughlin. "But the producers had to tell the audience not to laugh when they were misbehaving, because it only encouraged them." After five years off-camera, the Tuomy-Wilhoit fraternal twins, now 9, are attending auditions again. Not that they need the work: Full House left them with a nifty nest egg.
"Their investment manager has a talk with them every year," says mom Karen, 39, a kindergarten teacher in L.A. (The twins' father, Jeff, 39, is a commercial artist.) "I don't really think about the money," says Blake. "I'm going to use it for college."
Blake (above left) and Dylan got the job by kissing up to TV dad John Stamos (center). "At the last callback," recalls their mom, "Dylan crawled up on John's lap and hugged and kissed him." The twins have fond memories of Full House. "Acting is just fun," says Blake. Adds Dylan: "We got to wear cool clothes!"

Whatever a scene required, one of the Calabrese identical triplets could provide it. "Lexi was the crier," says mom Tami, 35. "Megan was always happy and giggling, and McKenzie was straight and dramatic." At 4, the girls are still working—shooting commercials and auditioning for shows. But Tami and her husband, Steve, 42, who own a boutique in an L.A. suburb, don't tell many people that their daughters are famous. "The other day a babysitter came over and said, 'Hi, my name is Katie,' " says Tami. "The girls giggled and said, 'But we're baby Katie.' She didn't have a clue what they were talking about. It was very cute."
On the set, says the triplets' mom (that's Megan, below, with TV parents Joe Lando and Jane Seymour), "there were always 10 people to hold them. They had it made."
MURPHY'S BABY, AVERY BROWN

Murphy Brown's little boy—made famous by then Vice President Dan Quayle's outrage over the glorification of single motherhood by choice—was played by a succession of children, most notably Oscar nominee Haley Joel Osment, who arrived in 1997 at age 9. Dyllan was the first baby to appear regularly, in 1994. After auditioning about 100 sets of twins, producers selected him because he was so chatty. "Dyllan just loved Candice," says his mom, Gina, 36, an artist. "He wouldn't stop talking to her!" Since leaving Murphy Brown in 1995, Dyllan, who lives in L.A. with Gina and dad Dan, 37, a printer, has appeared on Chicago Hope and in the 1998 movie Armageddon.
At the audition, Dyllan's mom recalls, "he went up to Candice Bergen [above] and said, 'I know you!' She said, 'Where do you know me from?' He told her, 'You know, Cookie Monster!' He'd seen her on Sesame Street" Bergen invited her new friend to see her "pretend office" and signaled thumbs-up as they walked off.

The first audition didn't seem promising. "Brennan had an explosive diaper," mom Hillary, 37 recalls. "It was everywhere." But the Felker twins appealed to Coach's stars and prevailed over 100 competitors. Now 4 and living in L.A. (dad David, 41, is a music programming director for a radio station; sisters Danielle and Deanna are 9 and 7, respectively), the boys love to watch tapes of their show. Do they remember playing their shared role? "I tell them, That's you;" says Hillary. "They seem to believe me."
Born 3% months premature and weighing less than 2 lbs. each, Brian and Brennan (below, with TV mom Shelley Fabares) weren't expected to survive (they are smaller than average but otherwise perfectly normal). "We were planning funerals," says their mother. "We always say they went from heart monitors to TV monitors."
HOPE AND MICHAEL'S BABY, JANEY STEADMAN

The girls were in their fourth year of thirtysomething when Janey got her first speaking lines. "We'd asked them to be quiet for so long, getting them to talk was like pulling teeth," recalls TV mom Mel Harris. Now 13 and living in Carthage, Mo., the identical twins have only vague memories of the show. "I can't remember anything, you know?" says Lacey. "I remember Mel was nice," says Brittany.
The twins are as inseparable as ever, even on their favorite subjects: choir, science and boys. But what they really want to do is act. "We left L.A. so they could have a normal life for a while," says their mother, Marilyn, 45, a homemaker, who still exchanges letters with Harris. (Dad Daniel, 45, is an IBM executive.) "We're looking to move back now."
"We're more like best friends than sisters," says Brittany (who with Lacey, below, played Ken Olin and Mel Harris's baby). Among their shared passions: a certain all-male pop group.
