It is quite easy for many shows to recast children while they are young and still growing so many fans don’t actually notice the switch. One child that was able to be switched under the radar was Baby Lily in Modern Family.

Lily was first played by twins Jaden and Ella Hiller, who weren’t actors at the time and didn’t come from a family of actors. They just answered an ad on Craigslist and were given the job. After a few years,  the novelty of the show must have worn off and the twins were no longer having fun, so the role was recast and in came Aubrey Anderson-Emmons, who is still portraying the role of Lily right now. It seems that the best option was to recast this character while she was young because many viewers weren’t originally aware that she was played by twins, so they wouldn’t have noticed the fact that her character was recast either.
