The winter toolkit: everything worth having before the first sniffle hits.
New term, fresh start: three need-to-knows for the parent running on empty
The sleep issue nobody talks about. Here's what's actually helping.
The immune health habits, nutritional support and small daily choices that can help your family through the season. Every year, winter takes parents by surprise. Not because we did not know it was coming. June follows May with the kind of reliability that should feel predictable by now. And yet, every year, the same thing happens. One child brings something home. The other finds it almost immediately. Then somehow, despite the handwashing, the vitamins and the very clear, very ignored instructions about not touching your face, the parent has it too. The good news is that there are practical things families can do to support their health and wellbeing through winter. Not miracle cures. Not dramatic interventions. Just everyday habits, appropriate nutritional support and small choices that can make a demanding season feel a little more manageable. This is the toolkit worth building before you need it. Because the ideal time to check the medicine cabinet is not 11pm on a Tuesday when someone has a temperature. It is now, while everyone is still upright and the pharmacy is open.
The habits
The unglamorous truth about supporting family health is that some of the most useful habits are also the least exciting.
They are not new. They have not been optimised by a start-up. They are simply the basics that tend to work best when they are practised consistently.
On sleep
Adequate sleep supports a child’s overall health, mood, concentration and normal immune function.
The same applies to parents, although family health advice has a habit of forgetting the person who was awake at 2am changing sheets or settling a cough.
Protecting sleep during winter is not always easy, and it will not prevent every illness. But creating a calm, consistent bedtime routine can give the whole family a stronger foundation for the weeks ahead.

Adventuring outdoors
Cold weather does not have to mean spending the entire season indoors.
Time outside gives children opportunities for movement, fresh air and natural light, all of which support general health and wellbeing. The practical challenge is choosing appropriate layers and convincing a toddler to keep them on for more than four minutes.
Handwashing as a habit
It remains one of the simplest ways to help reduce the spread of common infections.
It is also the thing children tend to rush, forget or interpret as briefly introducing two fingertips to running water.
Regular reminders, soap and enough time to wash properly are still worth prioritising.
“Make it fun,” says Nicolle Regent, Bio Island’s Customer Relations Manager and Nutritionist (Adv Dip. Nut Medicine). “Kids love games so turning it into a fun game or sing a silly song will make it feel less like a chore.”
“Happy Birthday is too long for an impatient toddler,” adds Hannah Smiroldo, Bio Island’s Product Training Co-Ordinator and Nutritionist (BHSc). “Come up with your own 10 second silly chant or use a visual timer/flashing light toy that stays by the sink. Once the light stops flashing the job is done.
“Children often learn best through play and modelling. Try washing your hands alongside your child or asking them to show you how to wash your hands properly – it gives them a sense of control and makes it more enjoyable. Letting them choose a fun soap can also help make handwashing something they look forward to.”
The habits do the heavy lifting. Handwashing, sleep, time outside, these are the things that matter most and cost the least. But if you’ve ever stood in front of the pharmacy shelf in June wondering whether any of it actually helps, you’re not alone. Here’s what’s actually worth knowing.
Supporting immune health
This is where the pharmacy shelf can become overwhelming.
There are brightly coloured labels, long ingredient lists and products that appear to promise everything from better concentration to a winter without a single sick day.
No supplement can guarantee that a child will not become unwell. Supplements should also complement, rather than replace, a balanced diet and appropriate medical care.
When a supplement is suitable for your child, understanding the nutrients on the label can help you make a more informed decision. So, what’s on the list?
First up, zinc
“Zinc is an essential mineral that plays a vital role in hundreds of processes throughout the body,” says Tori Jackson, Bio Island’s Product Educator and Nutritionist (BHSc, Clinical Nutrition). “It supports normal immune system function, protein synthesis, skin health, and cognitive function. It is particularly important that kids are getting enough zinc to help support normal growth and development and to maintain a healthy immune system especially during Winter.”
Adds Hannah: “Zinc is found in foods like meat, seafood, eggs, dairy, legumes, nuts and whole grains. Because zinc from animal foods is absorbed more efficiently, some children may struggle to get enough through diet alone, particularly if they’re fussy eaters or eat very little meat.”
And, Omega-3 fatty acids
Omega-3 fatty acids include DHA and EPA, which are commonly found in oily fish and fish oil products.
DHA contributes to normal brain and visual development. EPA and DHA also have broader roles within the body, including supporting normal cell function.
Cod liver oil contains omega-3 fatty acids as well as vitamins A and D. However, the amounts can vary between products, so it is important to check the label and avoid combining products that may result in excessive intake of fat-soluble vitamins.
“As a nutritionist, I always encourage a food-first approach, but I also understand that getting kids to regularly eat oily fish can be challenging,” says Tori.
“I like that Bio Island Cod Liver + Fish Oil provides the Omega-3 fatty acids EPA & DHA, as well as cod liver oil as a source of Vitamin A and D to support the immune system. It also contains Vitamin E as an added antioxidant. I love that it’s a comprehensive and practical option to help bridge nutritional gaps in kids from birth to 9+ years.”
Adds Hannah: “I really like how family-friendly this product is. It’s suitable from birth, and the fish-shaped softgel can be twisted or cut open so the contents can be mixed into food or drink for younger children, making it much easier for parents. It also provides a convenient combination of omega-3 fatty acids together with vitamins A, D and E in a single product.”
This product was developed over 15 years ago and includes D-alpha-tocopherol (vitamin E), which acts as an antioxidant supporting your child but also the other ingredients in the capsule! Vitamin E helps protect omega 3 oils from oxidation, for stability and quality.
The small daily choices
The best toolkit is the one that gets used. What most often interrupts a family routine is not a lack of motivation. It is friction.
The product is in the back of the cupboard. The instructions have disappeared. The morning gathers speed before anybody remembers what they intended to do.
A few small adjustments can make consistency easier.
Keep it visible, but store it safely. Choose a place that connects the product with an existing routine, while still following the storage directions and keeping all supplements out of children’s reach.
A visible reminder near the breakfast area may help, but supplements should never be left somewhere a child can access them independently.
Also, connect it to an established habit. Like, after breakfast. Before brushing teeth. Alongside the school bag check.
A new routine is often easier to remember when it is linked to something the family already does every day.
No toolkit can promise an illness-free winter. But putting supportive habits in place, checking the medicine cabinet and creating a simple routine can leave parents feeling more prepared when the season inevitably becomes busy.
