At first, it was very hard for little man to string them but he learns so fast! (Little man is 22 months and I wasn't sure if he would be old enough for this skill but it was great for him!) After a few minutes he was stringing them like a pro - and lost interest! What he really wanted to do was scoop the beads. So I brought out a spoon and some ice cube trays and we scooped away! I tried to get him to sort the colors but he was too distracted by scooping and stirring!
