When where nurseries created
Nurseries were created in early 1800s. The first known nursery was created by Friedrich Frbel in Germany. Nurseries are also known as pre-schools or kindergarten. Children between the age of 1 and 5 are taken care of by qualified teachers.
Probably way back in history. The rich aristocratic Roman especially would have "wet nurses" mind their children while they indulged. Valeria Messalina wife of Claudius for instance.
