A red-faced, grunting baby who hasn't pooed in days can rattle even the calmest parent. The reassuring news: in most cases what you're seeing is normal — and when it is true constipation, it's usually fixable at home. Here's how to tell the difference and what gently helps.
What constipation actually is
Constipation is about how the poo looks and feels, not how often it appears. Your baby may be constipated if their poos are:
- Hard, dry, or pellet-like (small balls)
- Painful to pass, with genuine straining, crying, or a tense tummy
- Coming alongside a firm, swollen belly or a baby who is off their feeds
What it is not: a baby who grunts, goes red and pulls up their legs but then passes a soft poo. That's just a little one learning to coordinate the muscles — it's called infant dyschezia and it's normal.
Frequency varies — a lot
There's a huge normal range, and it changes with how your baby is fed.
| Feeding | What's normal |
|---|---|
| Breastfed | Several a day in the early weeks, then can drop to one every few days — even up to a week — and still be soft. This is not constipation. |
| Formula-fed | Usually firmer and more regular; constipation is a little more common. |
| Starting solids (~6 mo) | Poos change colour, smell and texture as new foods arrive — some firming up is expected. |
The Australian Breastfeeding Association notes that a thriving, settled breastfed baby who is having soft poos infrequently does not need treatment.
Gentle things that help
Easing a stuck tummy
- Offer extra feeds — breast or formula. For babies over 6 months, you can offer small sips of cooled boiled water between feeds.
- Lie baby on their back and gently 'bicycle' their legs, then bring both knees up towards the tummy.
- Massage the tummy in slow, clockwise circles with warm hands.
- Try a warm bath to relax the muscles.
- On solids? Offer water and fibre-rich foods like pureed pear, prune, apricot or peas; ease back on rice cereal and banana for a few days.
A few important notes:
- Don't add extra water to formula or change the ratio to soften poos — always make formula to the exact instructions on the tin. Too-dilute or too-strong feeds can be harmful.
- No honey before 12 months — even as a "remedy" — because of the risk of infant botulism (AU, US and WHO all agree on this).
- Avoid laxatives, suppositories, rectal thermometers or anything inserted to "help things along" unless your doctor specifically tells you to.
Watch for dehydration too
Hard poos can go hand in hand with not enough fluid. Look for fewer wet nappies than usual (fewer than about 6 in 24 hours for a young baby), a dry mouth, no tears when crying, or unusual sleepiness. If you see these, contact your doctor promptly — see our dehydration-signs guide for the full list.
A quick reassurance
Most baby constipation settles with small tweaks at home, and an occasional firm poo is rarely a worry on its own. You know your baby best — if something feels off, or it's the middle of the night and you're unsure, it is always okay to ring your child-health nurse or GP for a chat.
