“I can't give my first child what they had as an only child”

The Myth: One Child, One Version of ChildhoodYou have a picture that doesn't fade: your first child as they are right now, sole focus of two adults, the whole house arranged around their rhythm. They read on the couch while you listen. They ask a question and get an answer. When they're sick, you're there. When they perform, you watch. This is their childhood. The moment you decide on a second child, this version ends. It doesn't evolve or expand—it ends. And because it was good, real, and theirs, you read that ending as a loss they'll carry. You're not worried they'll adjust. You're certain that what they're losing cannot be replaced by what they'll gain.

There are mornings you're in the other room. Bedtime takes longer because someone else needs something.

Picture them now, not at age four or seven, but as they are. Do they describe themselves as permanently diminished? Do they wish they'd remained an only child? Let the question sit without answering it for anyone else. You're not collecting proof that siblings are good. You're testing whether the thing…
