A baby registry is a list of items that expecting parents create to help friends and family know what they need for their new baby. This list typically includes essential items like diapers, clothing, toys, and nursery furniture. Many stores offer registry services, allowing parents to select items and share the list with loved ones. When friends and family want to give gifts, they can refer to the baby registry to choose something the parents actually want or need. This helps avoid duplicate gifts and ensures that the parents receive useful items as they prepare for the arrival of their baby.
