IS THE LEAP NCESSARY

well from the storys point to view the makers of aka may want to think tht way... but dont they think they will lose viewrship as they change the little one...now....?they wanna create autistic awareness, which they are doin so in such a fine way,,n tht happens only if us the viewrs stay glued to the tv.. but what if people who watch the show due to the little one.. n she gets replaced then where goes the awareness???huh??
