I find some of the post here about summer birthday kids and the kindergarten decision very interesting. My 2025 is an August birthday and we went through the same thoughts as many of you. He was very smart, emotionally ready for kindergarten, etc...etc. We sought feedback from anyone we could think to ask. Not just his preschool teachers but elementary schools teachers, middle school and highschool teachers and principals. The overwhelming majority said wait. They often said they never met a parent who regretted holding them back a year but saw many over the years who regretted sending them early. They pointed out the struggles of being late in every milestone, not the least of which was puberty.
So we waited, rather than enter kindergarten at barely 5 years old he entered at barely 6. No regrets....and so he is 2025, and not 2024.
