Sofia, your post is huge! I would like to address at least one thing. It's sometimes necessary for both the dad and the mom to work. I was a latchkey kid. My mom entered the workforce when I started kindergarten. Babysitters and neighbors watched me until I was in fifth grade or sixth grade. It was no big deal. This situation was very common for Generation X kids.
I totally understand. I had many latchkey days and Mom was very lucky I never got pregnant. She didn't work much, but she didn't like to stay home much, either. But many others were raised in random daycares, where there isn't always an incentive to do a good job. Neighbors had to do a good job if they wanted reciprocity with your parents. Babysitters have incentives to do a good job, if your parents know their parents. But, a daycare? There is no built-in accountability, aside from avoiding illegal actions like neglect and abuse. I'm glad you turned out well.
Did your daycare drive you to kindergarten? What time did you have to get to daycare in the mornings? How did you get to daycare from school?
