First find the total number of stocking stuffers one kid gets: 4 candy canes + 2 beanie babies + 1 book = <<4+2+1=7>>7 stocking stuffers

Then multiply the number of stocking stuffers per kid by the number of kids to find the total number: 7 stocking stuffers/kid * 3 kids = <<7*3=21>>21 stocking stuffers
