Only Child ProjectOnly Child ProjectOur reader poll turned out to be the best thing on this site. Here's more of it, one narrow question at a time.
Pick whichever one is actually bothering you, or answer them all. Each poll is anonymous, each lets you see live results right after you vote, and next to each one we've put what the real published research says, including where our own readers' answers might not match it. If they don't match, we say so and we don't pretend to know why. That's an invitation to tell us in the forum, not a gap we're going to paper over.
Research angle: a 2022 study of Spanish parents found that those content with having stopped at one child reported meaningfully better wellbeing than parents who wished they'd had more (Gómez-Ortiz & Sánchez-Sánchez, 2022), covered in The Overprotection Paradox. It doesn't tell us what share of parents feel that contentment in the first place, that's what this poll is for.
Most writing here is aimed at parents wondering how their child will turn out. This one's for adults who already grew up as an only child, see Only Child Pros and Cons and the Guilt Factor for the parent-guilt side of the same question.
Research angle: a 2021 study found mothers of only children reported higher anxiety and depression than mothers of multiple children (Levy, Murphy, Kamp, Langer & van Tilburg, 2021), covered in It's Not That Parents of Only Children Are Overprotective. We don't have our own poll data on this yet, so this one's a first for us.

Research angle: the same 2021 study above tested this directly by observing behavior rather than asking, and found only-child parents were not more protective, if anything they showed more minimization of their child's symptoms (Levy et al., 2021). If most of our readers rate themselves as more protective anyway, that's the belief-versus-behavior gap worth talking about.
Research angle: two reviews forty years apart found only children outperform, not underperform, siblinged kids on average, with no achievement deficit (Falbo & Polit, 1986; Stahnke, Williams & Meier, 2026), see A 1986 Meta-Analysis and a 2026 Systematic Review Say the Same Thing. A common parental fear points one way, the aggregate research points the other, this poll is about what parents actually feel, not about who's right.
