Copy-cat

My 3-year-old toddler is an extreme copy-cat! Spent Thanksgiving at some relatives' place, and my son got to play with two of his cousins. They were about 3 years, and 5 years older than him. He followed them around the whole time! The older cousin was a girl, and loved to dress my son up in dress-up clothes. My son was agreeable to whatever his older cousins wanted to do. The younger cousin was a boy, and wanted to be out in the backyard all the time. My son was happy to do that too! However, at some point, the cousins got tired of him constantly following them around, and would hide from him. I felt sorry for my son, but at the same time, was worried about him being such a huge "follower", and copy-cat! I wondered to myself if he would not develop his own identity. I was told by some friends though, that it was a typical 3-year-old thing! Oh well! Guess we shall see!
