How to Build the Perfect First Aid Kit for School-Age Children
What to include, how to organise it, where to keep it, and how to teach your child to use it — built around the injuries children actually get.
A good children’s first aid kit combines the Canadian Red Cross / AHA recommended contents — gloves, assorted bandages, sterile gauze, tape, antiseptic wipes, antibiotic ointment, saline wash, tweezers, scissors and a first aid guide — with family add-ons: children’s acetaminophen and ibuprofen, a children’s antihistamine, instant cold packs, an elastic wrap, and an emergency contact card listing allergies, medications and poison control. Keep it in a clearly marked, readily accessible container out of a toddler’s reach, and do a full check every 3 months. Add a prescribed epinephrine auto-injector only if your child has been prescribed one.
Every home with children needs a first aid kit. But not just any kit — a kit built for the injuries children actually get, stocked with supplies in sizes that fit small bodies, and organised so you can find what you need in the 30 seconds you have before a crying child loses patience.
This guide walks you through exactly what to include, how to organise it, where to keep it, and how to teach school-age children to use basic supplies themselves. The core contents below follow the Canadian Red Cross and American Heart Association (AHA 2024) recommended first-aid-kit lists, which are aligned with the Canadian CSA Z1220 kit standard.
The Complete First Aid Kit for Families with School-Age Children
Wound Care
- Disposable (latex-free) gloves — at least four pairs
- Adhesive bandages in assorted sizes — include character-themed ones for younger kids (a surprising motivator for cooperation)
- Butterfly closure strips for small cuts that might otherwise need stitches
- Sterile gauze pads (5×5 cm and 10×10 cm) and a roll of conforming/roller bandage
- Medical tape (paper tape is gentler on children’s skin)
- Antiseptic wipes (individually wrapped)
- Antibiotic ointment / topical wound gel (small single-use packets are most hygienic)
- Saline eye/wound wash (easier than running water for cleaning cuts on the go)
Contents per Canadian Red Cross / American Heart Association (AHA 2024) recommended first-aid-kit list, aligned with CSA Z1220.
Pain and Swelling
- Children’s ibuprofen (liquid for younger kids, chewable tablets for older kids)
- Children’s acetaminophen (have both — different situations call for different medications)
- Instant cold packs (at least three — they get used fast)
- Elastic wrap bandage (for sprains)
Allergy and Skin
- Children’s antihistamine (liquid or chewable)
- Hydrocortisone cream 1% (for insect bites, rashes, and mild skin irritation)
- Calamine lotion (for poison ivy, mosquito bites, and itchy skin)
- Aloe vera gel (for sunburn and minor burns)
- Prescribed epinephrine auto-injector if your child has one — keep two doses where possible and check the expiry every month
Tools
- Digital thermometer (instant-read forehead or ear type for quick use)
- Fine-pointed tweezers (for splinters and safe tick removal)
- Small scissors (blunt-tipped for safety around kids)
- Safety pins
- Disposable nitrile gloves (at least four pairs)
- Flashlight or penlight
Reference and Information
- First aid quick-reference card / first aid guide (laminated)
- Emergency contact information card — including your doctor, poison control (see the box below), and your child’s allergies and medications
- Medication dosing chart based on your child’s current weight — see the weight-dosing note above
Organisation and Maintenance
- Use a clear, labelled, watertight container — everyone in the family should be able to find and identify the kit instantly. In an emergency, a kit you can’t find fast might as well not exist.
- Store it in a consistent, accessible location — high enough that toddlers cannot reach medications, but accessible to adults and older children without a ladder
- Do a quarterly inventory — check expiry dates on medications, restock used supplies, and replace any items that have been opened or damaged
- Seasonal updates — add sunscreen and insect repellent in spring, extra cold packs in summer, and lip balm and hand warmers in winter
Storage & maintenance guidance per Canadian Red Cross and CSA Z1220 (kits should be clearly marked, readily accessible, and inspected regularly).
Teaching Children to Use Basic First Aid Supplies
School-age children can learn to handle minor injuries themselves — cleaning a scrape, applying a bandage, and using a cold pack. This builds independence and reduces panic in situations where an adult may not be immediately available. There is no single official age for each skill; the progression below is a general guide (in the spirit of Canadian Red Cross youth first-aid programs), and any hands-on skill is best taught by a certified instructor. Go at your own child’s pace.
- Younger children (roughly ages 6–8): Teach them to wash a cut with clean water, apply an adhesive bandage, hold a cold pack on a bump, and tell an adult about any injury
- Middle years (roughly ages 9–10): Add wound cleaning with antiseptic wipes, applying pressure to stop bleeding, and how to call 911 (what to say, what information to give)
- Older children (roughly ages 11–12): Introduce the recovery position, when an injury is too serious for home treatment, and — ideally through a certified youth first-aid course — simple bandaging and immobilisation
General progression modelled on Canadian Red Cross youth first-aid education; adapt to your own child and confirm skills through a certified course.
Frequently Asked Questions
What should be in a child’s first aid kit?
The Canadian Red Cross / AHA recommended contents include disposable (latex-free) gloves, adhesive bandages in multiple sizes, sterile gauze pads and a roller bandage, medical tape, antiseptic wipes, antibiotic ointment, saline eye/wound wash, a digital thermometer, tweezers, scissors, and a first aid guide. For a family with children, add children’s acetaminophen and ibuprofen, a children’s antihistamine, instant cold packs, an elastic wrap, and an emergency contact card with allergy and medication information. Include a prescribed epinephrine auto-injector if your child has been prescribed one.
How often should I check and restock my first aid kit?
Do a full inventory every three months. Check expiry dates on all medications, restock any items that have been used, and replace anything that has been opened or shows signs of damage. Do a seasonal update as well — add sunscreen and insect repellent in spring, and extra cold packs in summer. After any illness or injury in the family, check the kit immediately and replace what was used.
At what age can children use a first aid kit?
There is no single official age. As a general guide used in Canadian Red Cross youth programs, many children around ages six to eight can learn basic skills like washing a cut, applying an adhesive bandage, and telling an adult. Older children can gradually learn to clean wounds, apply pressure to stop bleeding, and how to call 911. Progress at your own child’s pace, and have any skills taught hands-on by a certified instructor. Medication should always be administered by or under the supervision of an adult.
Where should I keep a first aid kit at home?
Keep your main first aid kit in a consistent, clearly marked, readily accessible location — a kitchen cupboard, hallway closet, or bathroom cabinet are common choices. It should be high enough that toddlers cannot reach medications. Keep a second portable kit in the car. The most important thing is that everyone in the household knows where the kit is located, because in an emergency a kit you can’t find fast might as well not exist.
What is the poison control number in Ontario?
The Ontario Poison Centre can be reached at 1-800-268-9017, a free service available 24 hours a day. Across Canada you can also reach your regional poison centre through 1-844-764-7669. Save the number in your phone and include it on the emergency contact card in your first aid kit. Call if a child has swallowed, inhaled, or been exposed to a potentially toxic substance — and call 911 if the child is unresponsive, having trouble breathing, or seizing.
