  • Middle Childhood Milestone Social-Emotional

    Middle Childhood Milestone Social-Emotional
    2011 was the year I started middle school. This was a big transition for me, as some of my closest friends did not end up going to the same middle school that I did. I had to adjust quickly and learn how to make new friends, which was hard for me because I am a pretty shy person and I get intimidated easily. This shows social-emotional development as I had to learn how to get past my fears and make new friends and build new connections.
