Toddler Milestone Social

I was very good at playing with other kids at this age. One of my cousins is only a few months younger than I am, so when we were able to play together, I was able to share and teach him some things I knew. I also loved to play with my older cousins in Maryland.
This is an example of social development as I was learning how to play along with other kids and teens, and teach them what I knew.

At two years old, I enjoyed playing dress up and getting to put on jewelry as well as “makeup” which was just chapstick.

Toddler Milestone Cognitive

At around 2 and 1/2 years of age, I was reciting songs and rhymes I had heard. One example is that I knew all of "Take Me Out to the Ballgame" and loved to sing it at Diamondback games.
This is an example of cognitive development, as memorisation shows progress in that area.

Middle Childhood Milestone Physical

Nov 15, 2009

When I was in elementary school, my mom used to take my brother and I to Sedona every fall. We would spend time going hiking and exploring the area. It was one of my favorite things to do while I was growing up. This helped me develop my physical domain as we would make it a habit to go hiking, which requires physical exercise and ability.

Middle Childhood Milestone Language

Dec 10, 2009

My fourth grade year, we were allowed to choose a specialised music lesson that we wanted to learn. We had the options of band, orchestra, or choir. I picked choir, as I had always loved to sing. This began a long journey of being in choirs, learning how to read music and understanding solfege. This was an example of my language development as being in a choir required me to not only be able to read music and the lyrics that were on the page, but recite them as well.

Middle Childhood Milestone Cognitive

Apr 9, 2010

When I was in fourth grade, I was entered into my school's geography bee. The geography bee was a contest that they held, similar to that of a spelling bee, however instead of spelling, we were asked questions about geography. It was a competition where each class sent two kids, and out of everyone sent, I was fourth place. This is an example of cognitive development as it shows how I was able to memorize and recite information.

Middle Childhood Milestone Social-Emotional

Aug 8, 2011

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.

Adolescent Milestone Physical

Sep 29, 2014

Freshman year of high school was slightly overwhelming, I was struggling to gain confidence while being surrounded by people who had the goal of destroying that.
Freshman year I had PE class followed by choir, in which we would often be running dance numbers, so I had plenty of physical activity daily.
I was growing and became the tallest of my friends, which at first made me insecure, but I later learned how to love my height.
(Picture is my freshman year choir concert)

Adolescent Milestone Language

Oct 2, 2015

While I had been in choir since fourth grade, the idea of having a solo always terrified me. My sophomore year of high school, I put myself out there and actually got a solo in a concert.
Public speaking was always a big fear of mine, and presenting anything in front of a class caused a lot of anxiety. The opportunity to perform in front of so many people really helped me develop that aspect of my language domain.
(Picture is me performing my first solo)

Adolescent Milestone Cognitive

Dec 28, 2016

Soon after my sixteenth birthday, I got my license. I had been practicing since I had turned 15 1/2, and knew all of the rules of the road. The physical drivers test was a lot less nerve wracking for me than the permit test was.
This shows development in the cognitive domain as I had to memorize the rules of the road and learn how to navigate the busy roads in a safe way.
(Picture is me after getting my license)

Adolescent Milestone Social-Emotional

Apr 22, 2017

Throughout my high school years, I had many different groups of friends. My first two years of high school, I stayed close to my middle school friends, but junior year, I put myself out there and became friends with a whole new group of people.
Finding friend groups and building connections really helped develop my social-emotional domain. Because I was so shy and scared of rejection, making new friends helped me learn that it is worth it to put yourself out there.
