A while ago, on an old college friend’s blog, I stumbled across a comment that mentioned she didn’t want a second child, and “what would that say to our first child? That she isn’t good enough?”
I call bull.
One could equally argue that if you don’t have more than one child, it tells your child that he was too difficult and naughty for you to ever consider giving him siblings.
If you don’t want another child, that’s fine. Sorrowful, in my opinion, but fine. But don’t try to cast it up as a high and noble consideration for your child’s feelings, because kids just don’t think like that. Either argument is a modern ideology, not born out from experience.
