Encouraging frequent hand washing is the best practice to prevent a newborn from catching a cold from an older sibling. Hand hygiene is a crucial measure in stopping the transmission of respiratory illnesses, especially in a home environment where close contact is common. Newborns have immature immune systems and are more susceptible to infections, making it vital to minimize their exposure to pathogens.

Frequent hand washing by both the older sibling and caregivers can significantly lower the risk of spreading viruses that cause colds and other infections. This practice is effective because many germs are transmitted through direct contact with contaminated surfaces or hands.

While the presence of maternal antibodies is beneficial to the newborn's immunity, it does not directly prevent the transmission of infections from an older sibling who might be ill. Having the older sibling stay with their grandmother might provide temporary separation, but it does not address the fundamental issue of hygiene practices within the home. Similarly, having the older sibling wear a mask may reduce the risk of droplet transmission, but it is not as effective as consistent and proper hand hygiene, which is critical in everyday interactions, especially in the case of young children.
