The short answer is: not during the first winter RSV season, and with careful precautions at all times in the first months at home. I understand that this recommendation can feel socially isolating, particularly in a cultural context like Varanasi where a new baby is a community celebration and many family members and well-wishers naturally want to visit. But the recommendation is grounded in the specific biology of the premature immune system and the severity of consequences when infection occurs in a premature infant who is not yet ready for it. A premature baby's immune system is less mature than that of a term baby in several important ways. The passive immunity transferred from the mother across the placenta accumulates predominantly in the third trimester, so babies born significantly before term have received less of this protection. Their own immune response is slower and less vigorous. And as I described in the RSV section, their lung reserve is smaller, so respiratory infections that would produce mild illness in a term baby can produce severe distress requiring hospitalisation in a premature baby. The practical precautions I recommend for the first three months corrected age, and throughout the first RSV winter season: no visits from anyone with active respiratory symptoms, regardless of how mild they say the symptoms are; all visitors should wash hands thoroughly before holding the baby; visitors should not kiss the baby on the face or hands; crowds, markets, religious gatherings, and any enclosed public space with many people should be avoided; and where there is any doubt about a visitor's health, the visit should be postponed. Air travel carries specific additional risks and should be discussed with me individually before it is attempted. After the first RSV season has passed, and as the baby's corrected age moves past four to six months and their immune system has had more opportunity to develop, the restrictions can be eased progressively. The period of restriction is finite, and the consequences of a severe respiratory infection in those early months are not. The caution is temporary; the protection is permanent.
