Yes, gentle sunlight exposure can be beneficial for a newborn, mainly to support natural vitamin D production, but it should be done safely. You can expose the baby to early morning sunlight (before 10 AM) for about 10-15 minutes a day, keeping the baby lightly clothed and avoiding direct harsh sunlight on the face and eyes. Always ensure the baby is comfortable and not overheated. Avoid midday sun as it can be too strong for delicate skin. If you have concerns about vitamin D, your pediatrician may also recommend supplements.
