A Traditional Photo Done Over 33 Years Documents How Much Triplets Have Changed

Year 4

During their fourth birthday, the boys were already in their first year of school. Instead of sitting together side by side, the boys started to show off their personalities. Mark and Dennis still wore matching outfits while Peter was wearing another outfit. Instead of sitting beside his brothers, Peter decided to lay down.

They used another birthday sign this year too as you can see in this picture. This would be the birthday sign that the triplets would be using from that point on for many years to come.
