alt Hacker NewsYeah, the group dynamics of, say, a family with two children:
1. Kid A plays with Kid B
2. Kid A plays alone and Kid B plays alone
1. Kids A, B and C play together
2. Kid A plays with Kid B, Kid C plays alone
3. Kid A plays with Kid C, Kid B plays alone
4. Kid B plays with Kid C, Kid A plays alone
5. Kid A, Kid B and Kid C all play alone
Adding mom and dad as "players" would give us many more possible scenarios here (Kid A playing with mom, Kid B alone or with dad, etc).
I'm a father of two with a low income, and I would like to have a third child for precisely the above described reason. As a sociologist in my country put it -- somewhat harsh words maybe, but probably largely true: a single child might get spoiled, two children may start competing too heavily, but three children and above is company.
I disagree, when looking at 3-kids setup out there in the world. Ie my wife comes from such, she is the oldest and all 3 follow the typical 3 kids pattern - oldest was pushed into most responsibility to the point of trauma, middle one feels unappreciated and has inferiority complex as middle ones often do, and youngest is by huge margin the most spoiled one. This is the default for 3 kids that many parents end up with, unless fighting hard against this natural direction.
And yes a lot of interaction, but it doesn't guarantee anything further down the line - when long time adults youngest is still spoiled and selfish and not really a pleasant person to be around with for anybody, including siblings and their own mom. Middle one is scared to have kids, a decision that she may end up regretting later easily. And my wife is also carrying her part of the burden, won't bother you with details.
The grass is always greener behind the fence and all that.
