Similar to my kids. Both have fall birthdays. S23 started school at age 4, then they changed the age cutoff in our district and D26 was literally one day too young for the cutoff… so she was the oldest in her class most of the time.
However, S23 is my kid who has always been more mature than his classmates and ready for the next step… while D26 is the kid that sometimes wishes she’d had another year of just being a kid
