I was young for my year after being pushed ahead a grade. I did fine academically, socially, etc.<p>Two factors that make me want to start my future kids late:<p>-Social maturity: it&#x27;s way easier to handle social dynamics with a year extra of emotional maturity. Particularly important in high school and college<p>-Physical maturity: older kids often perform very well in high school sports. I, for example, grew and gained ~15-20lbs after I graduated high school (playing sports). That would have made my HS sports career much different, and therefore college prospects as well<p>I don&#x27;t see any reason to starting kids early for upper&#x2F;middle class folks, besides parent&#x27;s bragging rights.
