Maybe draw a number. Number all the packages when the child arrives. I for the first child. Mix them up in a hat and draw. Are you worried about playing favorites with the opening of gifts?
My little two year old nephew couldn't figure out why he had to open more gifts. He was too busy playing with the ones he already opened. LOL He would cry when he had to open another one. At your dot's age they know half the fun is opening.
