Thoughtfully chosen for every stage

Our Developmental Play Kits are designed around the skills your child is naturally working on, from early sensory exploration to stacking, posting and problem-solving.

Each kit includes carefully selected, age-appropriate toys backed by research, plus a printed Parent Guide to help you introduce them with confidence.

And the best part? They last much longer than the age on the box.

Many of the toys grow with your child, offering new ways to play as their skills develop.

Each new WonderBox doesn't replace the one before. Instead it adds to the collection of toys you can offer your little one in the months to come.

So while each kit covers a 2–3 month developmental stage, the value of the toys goes far beyond that age range.
