It could mean that they offered the role to someone and the family is still thinking it over (or accepted and then changed their mind). Or it could mean that they offered it to someone who turned it down and are now waiting for another family to accept. Or it could mean they found an adult that could play the part and are waiting to confirm that offer.
Honestly, I have no idea, so your guess is as good as mine.
