Constipation is one of the most common concerns parents bring up – and often one of the most frustrating, confusing and even misunderstood. Whether it’s a baby straining to pass stool, a toddler who refuses the potty, or an older child who seems chronically backed up, the story is familiar to many families. And yet, constipation is rarely just a digestive issue. It’s a message from the body – an invitation to look deeper.
In my practice, I often meet children with autism, ADHD, eczema, or sensory sensitivities whose constipation isn’t resolved with prunes or fibre supplements. But not only these children often need support on a much deeper level – one that acknowledges the powerful link between the gut, brain, nervous system, and daily rhythm.
What Constipation Really Is
Many people define constipation by how often a child has a bowel movement. But it’s more than just that. True gut health means that the body is able to eliminate easily, completely, and comfortably. If a child is holding in stool, straining to go, or passing dry, hard pellets – even if it happens daily – that’s constipation too.
The digestive process is a beautifully coordinated system, governed not only by muscles and food but also by the nervous system, hormones, microbiome, and emotional regulation. When this delicate balance is disrupted – whether by birth trauma, chronic stress, sensory overload, or inflammation – the bowels can slow down or shut down completely.
The Gut-Brain Connection
The gut and brain are in constant communication through the vagus nerve which is a kind of information superhighway that runs from the brainstem to the intestines. When a child feels safe, calm, and connected, the vagus nerve helps switch on the “rest and digest” system. This is when digestion flows, nutrients are absorbed, and elimination happens with ease.
But when a child is stuck in fight-or-flight mode perhaps due to sensory overwhelm, trauma, unresolved tension from birth, or ongoing stress, the body diverts energy away from digestion. Muscles tighten, peristalsis slows, and the bowel reflex is suppressed. Over time, this can lead to chronic constipation, especially in children who are already sensitive or neurodivergent.
Feeding Matters: Breastmilk, Formula, Solids
Breastmilk plays a vital role in shaping a baby’s healthy gut microbiome. It contains not only probiotics (beneficial bacteria) but also prebiotics, especially human milk oligosaccharides (HMOs), which selectively feed and encourage the growth of healthy gut flora like Bifidobacteria. These friendly microbes help crowd out harmful bacteria, reduce inflammation, support smooth bowel movements, and set the stage for long-term gut and immune health as well as brain development. Breastmilk also contains antimicrobial and anti-inflammatory compounds that gently protect the gut lining as it matures.
For formula-fed babies, you can still support a healthy gut microbiome by choosing formulas that include added prebiotics and probiotics, and by introducing prebiotic-rich weaning foods when solids are developmentally appropriate.
Constipation in young babies is often linked to feeding challenges – suboptimal latch, inadequate milk transfer and excess air intake can be the root causes of bloated tummy and impaired elimination. And this affects breastfed as well as bottle fed babies! Working with lactation consultant on positioning and attachment, identifying oral restrictions and implementing paced feeding for your bottle fed baby can be all that is needed to resolve their discomfort.
One common mistake is offering water too early. Babies under six months don’t need extra water. Breastmilk (as well as correctly prepared formula) is already perfectly hydrating and contains all the nutrients, fats, and enzymes a baby needs. Giving water too early can actually disrupt this balance, stress the kidneys, and lead to constipation.
When it comes to solids, timing and food choice are everything. Many babies become constipated when solids are introduced, especially if they’re started too early, in too large quantities or with processed foods like rice cereal or iron-fortified formulas. The immature gut simply isn’t ready for this type of load. Gentle first foods like meat stock, avocado, or soft-boiled egg yolk are more aligned with a baby’s natural digestive capacity.
Why Older Children Struggle Too
Constipation doesn’t always resolve with age. In fact, it can become a chronic pattern, particularly in children with autism, ADHD, or other complex health issues. Many of these children experience a combination of sensory processing challenges, low interoception (awareness of body cues), food aversions, and chronic stress. This makes it harder for them to recognise the need to go and even harder to act on it.
Sometimes, children begin to withhold stool because of a painful past experience – a hard poop, a scary toilet, or pressure from adults. Withholding leads to stool build-up, which stretches the rectum and dulls the natural urge to go. Over time, this cycle can lead to impaction, emotional distress, and even encopresis (leaking around a hard stool mass).
This is where a holistic approach becomes essential helping not just to soften the stool, but to rebuild the child’s sense of safety in their body and environment.
The Importance of Daily Rhythm
One of the most overlooked contributors to constipation is lifestyle and especially irregular routines. Our digestive system thrives on rhythm and predictability. The gastrocolic reflex, for instance, is a natural wave of bowel activity that happens after eating. But it can only be activated if a child is calm, connected to their body, and given time to sit and respond.
Morning light supports the circadian rhythm, boosts cortisol naturally, and stimulates the gastrocolic reflex (the urge to poop after eating)
Movement helps activate peristalsis
Toilet timing – encouraging your child to sit on the toilet after meals, in a calm setting, can help rebuild the brain-gut-toilet signal
Screens during meals, irregular routines, and chronic stress can all confuse the system and suppress gut signals.
Nutrition Goes Beyond Fibre
When it comes to nutrition, the goal is to soothe and nourish, not overwhelm. While fibre plays a role, not all fibre is helpful and too much of the wrong type can irritate a sensitive gut or create more bloating.
We often focus on soluble, soothing fibres from stewed fruits (like apples and pears), soaked chia or flax seeds, and soft-cooked vegetables. Healthy fats like ghee, olive oil, and avocado help lubricate the bowel. And of course, hydration is essential – but it must be consistent throughout the day, not just in bursts. Apart from water (with a pinch of sea salt or some lemon juice) you can include soups, juicy fruits (melons, grapes, cucumbers), coconut water.
We also reduce constipating and inflammatory foods like white flour snacks, processed dairy, and sugar-laden yoghurts. These not only slow digestion but can disrupt the microbiome and increase inflammation.
Gentle Remedies & Natural Support
There are many beautiful tools we can draw on to help the gut return to balance:
Herbal teas like fennel, chamomile, and marshmallow root can calm cramps, reduce gas, and soothe inflammation
Homeopathic remedies, chosen individually, can help reawaken the gut’s natural reflexes and release emotional tension linked to holding. For example Nux vomica for straining but no result; Silica for soft stool but hard to push out; Calc Carb for sluggish digestion in slower, more robust children.
Magnesium baths (with Epsom salts), abdominal massage, and craniosacral therapy can all support the body’s rhythms and vagal tone
One of the most powerful (and free!) tools? Sunlight. Morning light stimulates cortisol and serotonin – key regulators of the gut-brain connection. It also helps set the circadian rhythm, which influences melatonin production at night (another gut-healing hormone).
When To Seek Help
While many cases of constipation can be gently supported and resolved at home, some Red Flags should not be ignored. These include:
Blood in the stool
Severe pain, refusal to eat, or vomiting
Chronic withholding
Signs of gut inflammation or regression (behavioural changes, eczema flares, mucus in stool)
If in doubt, always reach out. Sometimes what’s needed is a combination of holistic care and professional guidance to prevent long-term gut issues and emotional patterns.
