This blog looks at what is genuinely the best baby formula for constipation in newborns, why the switch from breast milk or one tin to another can upset a baby’s tummy, and how we at BabyBest help parents find a gentler option. According to the NHS, constipation is one of the most common digestive complaints in the first year of life, and it is often triggered by a change in feeding routine rather than anything more serious. We know how worrying it feels watching your little one strain and struggle, so we have put together this straightforward guide, drawn from what we see parents ask us every day.
Objective
Our aim with this article is simple: to help you understand why formula-fed babies sometimes become constipated, what to look for in a tin of formula, and which gentle changes tend to bring the fastest relief.
Key Takeaways
- Tummy troubles in newborns are usually linked to protein type, iron levels, or how the formula is mixed, not to anything wrong with your baby.
- A gentle baby formula with easy-to-digest proteins and prebiotics can make stools noticeably softer within days.
- Goat Milk Formula and hypoallergenic options are worth considering if standard cow’s milk formula is not agreeing with your baby.
- Simple home measures such as tummy massage and correct formula mixing often work alongside a formula switch.
- Persistent constipation, blood in stool, or a distressed baby always warrants a call to your GP or health visitor.
What Is the Best Baby Formula for Constipation for Newborns?
There is no single “best” tin that suits every baby, but the formulas that tend to help most share a few traits: a protein that is partially broken down, added prebiotics, and no unnecessary bulking starches. Many parents we speak with find that a European organic formula, particularly a Goat Milk Formula, sits more comfortably because goat milk protein forms a softer curd in the stomach than standard cow’s milk protein, which can ease straining and hard stools.
What Causes Infant Constipation in Newborns?
This kind of tummy trouble rarely appears out of nowhere. In our experience, it usually comes down to one or more of the following:
- Protein type: Some proteins form firmer curds that are harder for a young digestive system to break down.
- Iron form: Certain iron compounds used in mass-market formulas can bind stools.
- Preparation errors: Formula mixed slightly too thick, using less water than instructed, thickens stools further.
- Sudden switching: Moving quickly between brands or from breast milk to formula without a gradual transition.
- Dehydration: Formula-fed babies sometimes need a little extra water once weaning begins, though this should always be confirmed with your health visitor first.
Is It the Protein, the Iron, or the Preparation?
If your baby has always been slightly constipated, the protein or iron source is the more likely culprit. If it started suddenly after a change of tin or a hotter spell of weather, preparation and hydration are worth checking first.
Which Ingredients Support an Easy Digestion Formula?
When you are reading the back of a tin, a formula built for easier digestion usually lists these features:
- Partially hydrolysed whey or A2 protein
- Galacto-oligosaccharides (GOS) or fructo-oligosaccharides (FOS), often labelled as prebiotics
- Beta-palmitate structured fat, or no palm oil at all
- Minimal added starches or maltodextrin
A formula for sensitive stomach needs will typically combine several of these points rather than relying on just one. Many parents also look for a digestive infant formula with added live cultures, which can support a more settled gut over the first few weeks of a switch.
If your baby’s current tin does not tick these boxes, browse our range of gentle formulas designed with sensitive tummies in mind. It is a small change that can make a genuinely noticeable difference within a matter of days.
How Do You Choose Between Goat Milk, Comfort, or Hypoallergenic Formula?
This is one of the questions we are asked most often. Goat milk formulas tend to suit babies with mild digestive discomfort, while “Comfort” ranges are formulated for constipation and colic together. Hypoallergenic (HA) formulas are a different category altogether and are intended for babies with a diagnosed cow’s milk protein allergy, so these should only be used on your GP’s advice. If you are still breastfeeding part time, it is also worth looking at options closer to natural composition, our guide to Formula Similar to Breast Milk covers this in more depth, as does our page on Organic Formula for Gassy Babies if wind and constipation tend to appear together.

What Role Does HiPP Play in Constipation Relief?
HiPP Comfort and HiPP AR ranges are among the most requested formulas for this exact concern, thanks to their reduced lactose and partially broken-down protein. You can read more about HiPP Formula Benefits on our shop page, including which stage suits your baby’s age.
What Offers the Best Constipation Relief for Babies?
Alongside a formula switch, a few gentle habits genuinely help:
- Warm bath followed by a tummy massage, using circular clockwise strokes
- Gentle bicycle-leg movements to encourage gas and stool movement
- Making sure each scoop is levelled and water quantities follow the tin’s instructions precisely
- A small amount of cooled boiled water between feeds once your baby is over six months, if advised by your health visitor
When Should You See a Doctor?
Book a GP appointment promptly if your baby has not passed a stool in more than three or four days, cries in evident pain, has blood in their nappy, or is not gaining weight as expected. These signs go beyond what a formula change alone should be expected to fix.
How Can You Switch Formulas Safely?
Introduce a new tin gradually over five to seven days, mixing increasing proportions of the new formula with the old one rather than swapping overnight. This gives your baby’s gut time to adjust and makes it far easier to judge whether the new formula is actually helping. Our full walkthrough on Choosing Formula for Your Baby covers this transition step by step.

Helping Your Baby Feel Comfortable Again
Constipation in a newborn is unsettling for any parent, but in most cases it responds well to a change of protein source, a closer look at how feeds are prepared, and a little patience during the transition. With the right combination of ingredients and a bit of gentle care at home, most babies find real comfort within a week or two.
Frequently Asked Questions
1. What is the best baby formula for constipation?
Formulas with partially hydrolysed protein, added prebiotics, and no unnecessary starches tend to work best, with goat milk and Comfort ranges among the most recommended by parents and health visitors alike.
2. How long does it take for a new formula to ease constipation?
Most babies show softer stools within three to seven days of a full switch, though a gradual transition may take slightly longer to show clear results.
3. Can I mix goat milk formula with my baby’s usual cow’s milk formula?
It is best to transition gradually rather than mixing two different formula types in the same bottle, so follow a step-by-step swap over about a week.
4. Is a soft stool baby formula the same as a laxative?
No, these formulas simply support easier digestion through gentler proteins and prebiotics; they are not medicated and do not act as a laxative.
5. When should constipation be treated as an emergency?
If your baby has severe pain, a swollen tummy, blood in their stool, or has not passed a stool for several days, contact your GP or health visitor straight away rather than waiting for a formula change to take effect.
