Our youngest son, born in August, could have gone to kindergarten when he was 5. We said, we don’t think so. Waited a year. Never regretted it.
My nephew’s oldest child was a boy born on August 26th. He is very bright and has a good personality. Already at age 3 years, 9 months, he passed the so-called screening for being ready for Kindergarten. The next year he passed again. But the parents kept him back so when he began school he was 6 years and 7 days old.
It was a good decision because he is physically a smaller child, and needed to grow a bit to match the other kids.
