By designating the other parent as the EOR, there are inherent advantages in terms of bonding and familiarity. The EOR, being intimately involved in the care of their child, possesses a deep understanding of the individual's unique needs, preferences, and routines. This familiarity fosters a strong bond between the EOR and the individual in need, ensuring a higher level of comfort and trust in the caregiving relationship. In contrast, a non-live-in EOR, lacking the same level of familiarity and connection, may face challenges in establishing a meaningful caregiving dynamic. The emotional well-being and sense of security for the individual in need are best facilitated when the EOR parent assumes the other role, fostering a nurturing and supportive environment.
