Having children skip several grades is generally a bad idea even if they are very intelligent

Many parents do this if their kid is “smart” enough because they think it will give them a head start or something. i suppose that 1 or 2 grades in pre/elementary school is fine, but anything past that will put both girls and boys at a social disadvantage. being years younger than your peers is a huge deal when you are school aged is a way bigger deal compared to when you’re already an adult.
