Your post made me think.
When I went to school for the first time my mother cried.
When I went away to college for the first time, she cried hysterically. Not just when I went to college for the first time. When I came home to visit, about once every month, she cried hysterically every time that I went back on the bus. This was over four years.
When I was 25 and I met a man from Canada, and we decided to move to Canada for a year. My mother cried for weeks on end.
I am writing this to point out that each of these experiences were ruined by my mother. I was excited about college, until my mother made it all about her, and dragged me down with her crying.
I wws excited about going to canada, until my mother ruined that for me, and brought me down with her terrible crying for weeks.
I was never allowed to enjoy these experiences.
The point is, you don't own your child. They are an independent human being.
Think of your child, not of yourself and how you are thinking. He will be excited to go to school and meet new friends
