A baby registry is a list of items that expecting parents create to help friends and family purchase gifts for their upcoming arrival. The registry typically includes essential items such as diapers, wipes, blankets, clothing, and other necessary supplies for newborns. It can also include larger items like strollers, car seats, and cribs. Parents often register for these items at a store or online to make it easier for friends and family to purchase gifts that they know the parents will need.
