Why we make this

Fewer toys. More play.

After a second baby and a burnout, Biggest Little founder Stephanie Fu cleared her Brooklyn apartment down to a handful of open-ended toys and kept it that way for almost two years. Her children played more, not less. And they kept going back to the plainest things, the ones that left the most room to imagine.

That is the heart of what we do. We take the oldest and simplest toys, a ball, a scarf, the box it came in, and design them well enough that you end up playing with them too.
