First day of school

1st day of school for my elder son. Jan 4. He is 20 months old. He was ok when he entered. Particularly because he was distracted by toys. When I left, I told him bye bye. He was too distracted by toys so didn't even look at me. After 20 mins we went back and heard a lot of crying outside the classroom door. I kept praying he's not crying. HAHAHAA. So when we pick him up, he came out of the classroom crying so badly. With running nose and teary red eyes. Teacher had to wipe them clean before dismissing him. He kept shouting mama when he saw me standing outside of the classroom. Then took his shoes and wanted to wear them badly to faster leave the place. Lol.
