Another early starter checking in - my birthday is in early January and the cut-off date in my school district was September 1, so I was about four months younger than the next youngest when I started kindergarten at age four.
And honestly, I think it really depends on the kid and the circumstances. There were both good and bad aspects about starting early but they were so dependent on my individual personality that I don’t think anyone but those who know your kid can really decide. I’ll give you some of the anecdotal highlights of the experience, though; maybe there’s something you haven’t considered.
Academically, there was never a single problem. I showed up on day one ready to go and 13 years later graduated valedictorian of my high school class. Like amarinth I think holding back a year would have done nothing for me academically speaking and might even have been harmful.
Emotionally/socially is more of a mixed bag. Aside from a spectacular meltdown on day one of kindergarten (which almost put the kibosh on the whole process - my parents had to beg the administration to give me another chance) I didn’t have any behavioral issues. Sitting still in class and paying attention and following instructions were all non-problems, at least from day two onward.
Socially I’ve always been introverted and a bit immature, but I honestly think that would have been the case whether I started kindergarten at four or 14. Maybe if I had started school with my peer group I might have been slightly more outgoing, but I really doubt it - it’s just not my nature. I certainly don’t think I was damaged or emotionally stunted in any way.
It did give the other kids an easy label. My family moved between my second and third grade years, so I was the ‘new kid’ on the first day of third grade, and once the others found out that I was 7 instead of 8 years old, I became the target of some pretty vicious teasing. Eventually the name-calling and taunts got bad enough that the teacher would announce recess and I would burst into tears, which really didn’t convince anyone that they shouldn’t be calling me ‘baby’ at every opportunity.
But on the other hand, kids are awful generally - if I wasn’t the baby, I would have been the fat kid or the smart kid or the teacher’s pet. The other kids lost interest after a month or two and I made friends and moved on with my life. And being the youngest could be a bonus too - I was proud of my academic achievements and I got a little extra boost from also being the youngest. My parents were proud of me too - not in the ‘my kid is only as good as her GPA’ way, but in the good way.
Puberty was really kind of a non-issue. There’s such a range in the ages people start puberty that starting your kid in school at age four, five or six doesn’t have anything to do with whether they’ll go through puberty in lockstep with their peers at 13. I was the youngest in my class but went through the trauma at about the same time everyone else did. The kids who were late-bloomers weren’t any older or younger on average than the rest of us.
As for things that are age-limited, most of the time it wasn’t a big deal. My mom made a phone call in the first grade and I started Brownie scouts along with the other girls in my class, despite being technically too young for Brownies. I was allowed to sign up for the local youth softball league for 9-12 year olds, despite being only eight. However, I did eventually quit softball at 12 because all my softball friends had moved on to the 13 year old team, which was a traveling team and stricter about age limits. Driving wasn’t really a big deal - I had older friends who could drive, and by the time I was in high school people tended to have friends from different grade levels, so I wasn’t the only one in my group of friends who wasn’t old enough to drive. The most annoying age-related stuff was not being old enough to vote in the presidential elections during my first year of college on a very politically active campus (though I would have been just as annoyed had I been a senior in high school) and being 21 later than a lot of my college friends (though, again, my college friends had a range of ages and I certainly didn’t have to get boozy at home by myself - there were always plenty of other 20 year olds without fakes around to get boozy with ).
Do I regret missing out on an extra year of carefree childhood? No. I barely remember being four years old. If I were to have an extra year somehow, I’d rather it be when I’m old enough to appreciate it. At this point, I regret not taking a year off between college and professional school, not between nursery school and kindergarten.
In the end, I’m glad I started early, but I don’t think it really matters in the long run. There wasn’t really an actual downside (but again, a kid needs the right temperament in order for there not to be one, which may be hard to judge) and the upside is that I’ll have finished a university degree and a professional degree at 24, which for me is something I place value on but for someone else it might not matter. I think getting high school out of the way at 17 wasn’t a bad thing, no matter what I was going to do next.
And, um, hi. I’m newish. Been lurking for years but finally there’s a question I’ve got firsthand anecdotal information on. Cheers!
