As the twins develop into toddlers, the parents of the family are also beginning to understand their characteristics. Bill and Sarah acknowledge that Jillian is the family's daredevil who enjoys climbing everything and playing practical jokes on the other members. Jenna, on the other hand, seems to be the complete opposite. She enjoys taking good care of her possessions. However, both constantly seem to feel the desire to contact one another. The family is now accustomed to seeing Jenna and Jillian practically everywhere they go while holding hands.
