The "loose parts" idea, named by the architect Simon Nicholson in 1971, holds up well: the more a material can be used in different ways, the more inventiveness it draws out of a child. Toys built for one purpose mostly produce one kind of play. A cardboard box is a den, a car, a cradle, a stage, and a hat depending on the day. Before buying anything, look in the recycling, the airing cupboard, and the back of the kitchen drawer. Healthbooq helps families spot creative play in everyday materials.
Cardboard Boxes
Appliance-sized boxes. A box big enough to sit in is a den, a boat, a rocket, a shop counter. Cut a window or two with a craft knife (you, not the child). Draw a steering wheel on one wall. Leave it in the corner of the room for a week and watch the play shift across days — the den becomes a stage becomes a bus.
Cereal-and-shoebox-sized boxes. Stackable, knockable, fillable. Tape several together and you have an apartment block. Cut a slot in the lid and it's a posting toy. Stuff it with crumpled paper and small toys disappear inside it for the next half-hour.
Cardboard tubes. Toilet roll, kitchen roll, the long ones from wrapping paper. They're telescopes, trumpets, ramps, drawbridges. Tape three to a wall on a slope and roll a marble through them; this is half an afternoon. Dipped in paint, the cut end stamps perfect circles.
Flat cardboard sheets. Cutting and tearing practice for fingers that need it. Painting backgrounds. Cut into puzzle pieces after a drawing. Propped against a chair, a wall.
A note on safety: the craft knife is yours. The play is theirs.
Fabrics
Sheets, tablecloths, old curtains. A sheet over two chairs is a den. A different sheet over the same two chairs is a different game. Children at this age care more about the enclosure than its quality. Add a torch and the den becomes a cinema.
Scarves, ribbons, fabric scraps. Capes, swords, baby blankets, lassos, sashes. Small children twirl them, drag them, drape them on stuffed animals, layer translucent ones over a flashlight to mix colours on the wall. Texture matters: cotton, silk, wool, fleece each invite different handling.
Old clothes, hats, bags. Dress-up doesn't need a costume box from a shop. Your old hat, a bag, sunglasses, a scarf — that's the entire kit. Sorting them by colour or type is a separate game most children fall into without prompting.
A small basket of varied fabrics in a corner gets used more than the same fabrics folded in a drawer.
Lids
Jar and bottle lids. Save them. After a few weeks you'll have a collection of fifty in different sizes and colours, and a collection of fifty lids is a sorting game, a stacking game, a counting set, a circle-stamp set, a wheels-for-a-cardboard-car set. Matching a lid to its jar is hand-and-eye work that children will do for twenty minutes.
Posting and filling. Cut a lid-sized slot in the top of a box and you've made the toy that early-Montessori-trained eighteen-month-olds will choose over almost anything else. Fill, tip out, fill again. The repetition is the point — they're confirming object permanence and practising precise grasp.
Combinations. Lids stack inside larger boxes. They become the wheels on a cereal-box car. They're tokens in a made-up game. They print circles in paint. The flexibility is the value.
Why This Works
These materials don't have a correct use. A wooden train says "push me along a track." A box says nothing, so the child has to say something, and the saying is the play. Open-ended materials draw out planning, naming, narration, and problem-solving in a way single-purpose toys mostly don't. They also cost nothing, which means you can have many of them, which is how loose-parts play gets interesting in the first place.
One last thing: don't tidy too fast. A half-built fabric den or a row of lids on the rug isn't mess — it's an unfinished sentence. If you can leave it until the next day, the play often picks up where it left off, and that continuity is its own developmental win.
Key Takeaways
Boxes, fabrics, and lids are open-ended in a way most toys aren't — they don't tell the child what they are, so the child has to decide. Most homes already have all three. The developmental return per dollar is hard to beat.
