Wooden Rosary for Children make a great first communion gift ideas. These are usually large bright beads that fit little finger well. They also have non toxic paint and are big enough that it will be hard to swallow beads as a tradition rosary would be.
Family rosary time is important for a family as the children grow and these rosaries make a great way for children to participate. It is recommended that children be taught the rosary early and a children's rosary makes a great way to do that.
