The were big stars when they were young, but never carried on to be adult stars.

people get so used to them as a certain role, so it makes it hard for them to get serious work

They end up being labeled and nobody wants them.For example, when that kid that plays Harry Potter is 30 whenever someone sees them they are gonna be like "Hey! It's Harry Potter!"Directors and producers don't like that.

some get burned outgood example: the olson twinseveryone loved them as the baby in Full House but the moment they grew up they pretty much lost their life in hollywood.I like how Corey Haim and Corey Feldmen are doing that show "The two Coreys" about their lives as adults and what they go through as friends and problems.

can't bear the load of stardom at such an early stage........loads of unjustified demand and expectation........form a stereotype as a child actor......never ever able to break that prototype........enough of it!!

I guess people just forget them. When they hit their teen years, they don't get roles. So I guess thats y. Oh and to the person who said about that Harry Potter kid, don't you dare say a word against Daniel Radcliffe. He's just not known as the HP guy. He's coming in plays and alot of different movies. So shut up you SOB. Long live Harry Potter.You can dance .. you can jive .. having the time of your lifeSee that girl .. watch that scene .. diggin' the dancing queen ♥♥♥.

it is because that they have already receive the richness and fame that what they want and dreamed of.

I Don't Know but I hope Nathan Kress becomes an adult actor

I think it really varies.I think some kids outgrow their (or stop being) "cute" status. Some seem to be typecast and can never escape. Examples include the Olsen twins, "Webster" and Gary Coleman.Some seem to get to into the partying and not the acting such as Lindsay Lohan and River Phoenix.Some seem addicted to fame for fames sake and not because they're actually talented. The parents are addicted to fame or pushing their kids.Generally speaking the kids that have "sensible" parents who don't stick them in front of the paparazzi viewfinders every five seconds seem to do better as adults.Daniel Radcliffe may survive - as long as he can do other rolls aside from Harry Potter.
