A foundling hospital is a place where babies who are abandoned or left without a parent or caregiver are taken care of. It's like a special house for these babies. It's a safe and warm place where they are given food, clothes, and attention from people who are trained to take care of them. The people who work there make sure that the babies are healthy and comfortable until they can find someone to take care of them permanently, like a family who wants to adopt them. The foundling hospital is a place where these babies can have a better chance at life, even if they don't have parents at first.
