Basic First Aid for Kids | First Aid Training!

What you need
Adult supervision required, cardboard, cloth strips or bandana, scissors, stuffed toy or mannequin, tape

Step 1

Gather all materials and set them on a clean flat table.

Step 2

Lay the stuffed toy or mannequin on its back with the "injured" arm resting beside the body.

Step 3

Place a piece of cardboard along the toy's arm so it extends past the wrist and past the elbow.

Step 4

Carefully cut the cardboard to the length you placed along the arm.

Step 5

Make the cardboard edges rounded so they are not sharp.

Step 6

Fold one cloth strip several times to make a soft padded strip.

Step 7

Lay the folded cloth on the inner side of the cardboard to create a padded splint.

Step 8

Slide the padded cardboard under the arm so it supports the arm from wrist to elbow.

Step 9

Gently hold the toy's arm straight against the splint.

Step 10

Wrap tape around the arm and splint in two or three places to keep them together.

Step 11

Look to make sure the arm is held straight and the splint feels snug and secure.

Step 12

Share a photo of your finished splint on DIY.org.

Help!?

What can we use if we don't have cardboard, cloth strips, or tape as listed in the materials?

Use a stiff magazine cover or a thin plastic folder cut to wrist-to-elbow length as the splint, fold a clean sock or small hand towel for the padded cloth strip, and secure everything with masking tape, string, or a bandage following the sliding and wrapping steps.

What should we do if the splint keeps slipping or the tape doesn't hold when we wrap the toy's arm?

Press the folded cloth padding firmly against the cardboard, make sure the cardboard extends past both wrist and elbow as in steps 2–4, then wrap tape tightly in two or three places and smooth the ends so the arm feels snug and secure per step 9.

How can we adapt this immobilization activity for different age groups?

For preschoolers have an adult pre-cut and round the cardboard and fold the padding (steps 3–6) while older children can measure, cut, and decorate the cardboard themselves and practice taping the splint securely before sharing the photo on DIY.org.

How can we extend or personalize the finished splint activity after wrapping the toy's arm?

Decorate the cardboard before padding (step 4), add a tied cloth sling to support the splinted arm, and write the child's name and 'first aid practice' on the splint before taking the photo to share.

Facts about first aid for kids

⏱️ Quick stabilization is key—immobilize an injured limb before moving the person whenever it's safe to do so.

🩹 A simple splint can reduce pain and prevent further injury by keeping broken or sprained limbs from moving.

📦 Corrugated cardboard is lightweight yet strong—layering and folding it makes a sturdy DIY splint material.

🧸 Practicing on stuffed animals or manikins helps kids learn first aid skills calmly and builds confidence.

🧵 Soft cloth or padding between the limb and splint prevents pressure sores and makes the splint more comfortable.

How do you practice making a simple arm splint using cardboard, cloth, and tape on a stuffed toy or mannequin?

Start by pretending the stuffed toy has an injured arm. Keep the arm in a comfortable, natural position. Place soft padding (cloth or gauze) around the limb. Lay two flat pieces of cardboard—one on each side of the arm—to act as splints. Wrap a wide cloth or triangular bandage snugly (but not tightly) around the splints to hold them in place. Secure with tape over the cloth. Check that fingers aren’t cut off and circulation looks normal. Practice communicating with the “patient” throughout.

What materials do I need for a practice arm splint activity?

You’ll need sturdy but safe supplies: two flat pieces of cardboard or thin craft foam for splints, soft cloth or towels for padding, a triangular bandage or wide cloth to wrap, and medical tape or masking tape to secure. Optional: scissors (adult use), marker to label sides, and a stuffed toy or mannequin. Keep sharp tools away from young children and use rounded cardboard edges to avoid accidental pokes.

What ages is this activity suitable for?

This activity is great for a wide age range. Preschoolers (4–6) can role-play and help hold padding with close adult supervision. School-age kids (7–11) can practice arranging padding and wrapping with guidance. Tweens and teens (12+) can learn more step-by-step technique and safety checks. Always supervise younger children and emphasize that this is practice only—real injuries need adult help or trained first responders.

What safety tips and benefits are there when practicing making splints?

Benefits include learning basic first-aid steps, improving fine motor skills, and building confidence in emergencies. Safety tips: never practice splinting on a real injured limb without adult or professional guidance; use soft padding to prevent pokes; don’t wrap too tightly—check circulation if practicing on people; avoid sharp edges on cardboard; and keep all scissors and tape dispensers handled by adults. Reinforce calling for help in a real injury.
