Managing Hypoglycaemia in Young Children: Tips and Strategies
Share
Low blood sugar, or hypoglycaemia, can be one of the most worrying parts of managing Type 1 Diabetes in children. When your child is very young, it’s even harder: they may not recognise the symptoms, or struggle to explain how they feel.
In this guide, we’ll walk you through everything parents and carers need to know about hypoglycaemia: what causes it, how to treat it quickly and how to reduce its frequency and stress, especially at home, school, or during sleep.
What Is Hypoglycaemia?
Hypoglycaemia happens when blood sugar levels fall too low, generally below 4.0 mmol/L. The brain depends on glucose for energy so when levels drop, symptoms can come on quickly and feel intense.
For young children, hypos can happen more often because:
- They’re more sensitive to insulin
- Their activity and eating patterns can be unpredictable
- They may not notice or communicate symptoms clearly
Common Causes of Low Blood Sugar in Kids
- Too much insulin for the amount of carbs eaten
- Skipping or delaying meals/snacks
- Increased physical activity
- Hot weather or bathing
- Illness or vomiting
- Overcorrecting a high blood sugar
Understanding what led to the hypo can help prevent it happening again.
Signs of Hypoglycaemia in Young Children
Every child is different, but common symptoms can include:
- Shakiness or wobbly legs
- Pale or sweaty skin
- Hunger
- Mood swings or sudden crying
- Drowsiness or confusion
- Slurred speech or lack of coordination
- Difficulty concentrating
- Behaviour that’s “not like them”
Some children may not show symptoms at all, known as hypo unawareness, which is why CGMs and gentle alert systems like Glowcose can be so helpful.
Immediate Treatment: The 15-15 Rule
- Give 15g of fast-acting carbs (for example, glucose tablets, fruit juice, or a fizzy drink).
- Wait 15 minutes, then recheck blood sugar.
- If still below 4.0 mmol/L, repeat the treatment.
- Once levels are above 4.0 mmol/L, give a longer-acting snack (such as crackers or toast) to maintain balance.
Stay calm, and always follow your child’s individual care plan.
How CGMs and Glowcose Can Help
A Continuous Glucose Monitor (CGM) offers real-time alerts when blood sugar starts to drop, giving you more time to act before a full hypo sets in.
Glowcose adds a layer of calm by turning blood glucose level data into an easy-to-understand colour cue. Especially helpful at night, Glowcose lets you stay informed without loud alarms or disturbed sleep — one glance and you’ll know whether you need to intervene.
Explore Glowcose to learn how it complements your existing CGM setup and brings more peace of mind into your daily routine.
Practical Tips to Reduce Hypo Frequency
- Keep consistent meal and snack times
- Talk to your care team about adjusting insulin ratios
- Use CGM trend arrows to predict dips
- Pack hypo kits for school, sleepovers, or outings
- Teach older siblings or family members what to do
- Offer praise, not panic — reassure your child that hypos are normal and treatable
Communicating With Schools and Carers
Provide a written Hypo Action Plan that includes:
- Signs to watch for
- When and how to treat
- Emergency contact details
- Location of hypo treatment supplies
Many schools welcome training sessions or printed resources — speak to your child’s diabetes nurse about support materials for school or afterschool clubs.
FAQs: Hypoglycaemia in Young Children
How can I tell if my toddler is having a hypo?
Young children often can’t articulate how they’re feeling. Look for signs like sudden tiredness, unusual fussiness, pale skin, or loss of coordination. Some may cry, hide, or say their tummy hurts. If in doubt, test their blood sugar or check the CGM. Keeping a record of your child’s personal signs can help others (like teachers or grandparents) learn what to watch for too.
What if my child refuses hypo treatment?
This can be tough, especially with toddlers who may not understand what’s happening. Try offering something they enjoy, like a favourite juice box, and remain calm. Distraction (a cartoon, music, or comfort toy) can help them take the treatment. If they’re unable or unwilling, discuss emergency options such as glucagon with your diabetes team, and ensure all caregivers know how to use it.
Are night-time hypos dangerous?
They can be, especially if undetected — which is why nighttime monitoring is crucial. Using CGMs and tools like Glowcose is incredibly helpful here. Night hypos can cause confusion, night sweats, or nightmares. If your child has regular night-time dips, your paediatric diabetes team may adjust their evening insulin or suggest a bedtime snack.
Can exercise cause hypos hours later?
Yes — children can experience delayed hypos several hours after physical activity, especially after intense or unfamiliar exercise. Keep an eye on CGM trends and consider extra snacks post-activity. Inform school staff and coaches about this too, especially on sports or PE days.
What if a hypo happens at school or nursery?
Make sure your child’s carers or teachers are trained in recognising and treating hypos. Provide a clear action plan, keep hypo supplies accessible, and maintain open communication with staff. Most schools are happy to support you when they feel confident and well-informed.
How can I prevent frequent hypos?
Frequent hypos may indicate a need to adjust insulin or food ratios. Review trends with your diabetes team and keep detailed records of meals, activity and doses. Balancing meals and including slow-releasing carbohydrates can help maintain steadier levels throughout the day.
Can emotional stress trigger hypos?
While stress more commonly causes highs, in some children overexcitement, fear, or sensory overload may lead to a hypo — especially when paired with missed meals or activity. If this seems to be a pattern, keep extra snacks nearby and speak to your care team about possible adjustments.
Is it OK to “overtreat” a hypo?
It’s understandable to panic, but too much sugar can lead to a rebound high, which can be uncomfortable and may require correction. Stick to the 15g quick sugar, wait 15 minutes and test again. It takes practice, but the 15-15 rule is the safest approach.
Final Thoughts
Hypoglycaemia can feel scary, but with calm preparation, real-time monitoring and a clear plan, it becomes a manageable part of daily diabetes care.
You’re not alone. Families across the world are navigating this too, and tools like Glowcose can offer a simple, non-invasive way to stay on top of your child’s glucose levels, day and night.
