When your baby cries after feeds, it is understandable to search for the best formula milk for colic. But there is no single formula shown to fix colic for every baby. The first step is to check feeding and health, then decide whether changing milk has a clear purpose.
Is there a best formula milk for colic babies?
Colic describes excessive crying in an otherwise healthy baby. It often improves by three to four months, but crying also has other causes. The NHS colic guide recommends getting advice when you are worried, struggling to cope, or your baby is not growing as expected.
The ESPGHAN Nutrition Committee’s 2024 position paper does not advise specialised formula for colic because clinical evidence is insufficient. It also advises against stopping breastfeeding to treat these digestive symptoms. This is why an “anti-colic” marketing claim is not enough to justify a purchase.
A Cochrane review of dietary changes found small, generally poor-quality studies and inconsistent results. It could not recommend the dietary interventions assessed. Its evidence search ended in 2018; the later ESPGHAN guidance above is also relevant. An individual improvement after switching does not establish that the formula caused it, particularly when crying changes with age.
When crying needs medical help
Seek emergency care if your baby has difficulty breathing, becomes blue or grey, is very hard to wake, or has a weak or unusual high-pitched cry. A temperature of 38°C or more in a baby under three months also needs immediate medical assessment. Do not wait to test a different formula.
Seek prompt advice for poor feeding, fewer wet nappies, persistent vomiting, blood in stools or poor weight gain. If your baby seems seriously unwell, use your local emergency service. See NHS signs of serious illness in young children.
Formula types: what the labels mean
| Type | How it fits the decision |
|---|---|
| Standard infant formula | A routine feeding option; crying alone does not prove it needs replacing. |
| Comfort / partially hydrolysed | Protein is partly broken down. This is not a treatment for diagnosed milk-protein allergy. |
| Lactose-free or reduced-lactose | Changes the milk sugar. It does not necessarily remove milk protein or make the product suitable for milk allergy. |
| Extensively hydrolysed or amino-acid formula | Specialist options for particular medical needs, including some milk allergies. A clinician should choose the type. |
| Goat-milk formula | Not an allergy workaround or an established colic treatment. |
The FDA’s routine and specialty formula overview explains the categories. For the goat-milk distinction, read our goat formula benefits and limitations guide.
What about Nutramigen and Similac Alimentum?
These names appeared in the old product list. The FDA lists Nutramigen and Alimentum hypoallergenic infant formulas among products for special dietary needs. That does not make either a general “best for colic” choice. Exact powder and liquid versions matter; follow the prescription or clinician’s product instructions rather than an online ranking.
When a clinician may consider milk allergy
Colic and allergy symptoms can overlap. In its 2024 cow’s milk allergy position paper, ESPGHAN discusses a time-limited elimination trial when additional symptoms make allergy plausible, followed by a planned diagnostic challenge. Improvement during an elimination alone does not confirm allergy.
Ask your paediatrician what is being assessed, which formula to use, how long to trial it and when to review the result. Reintroduction must follow their instructions; do not attempt a home challenge after a severe or immediate reaction. A breastfeeding parent should not start a broad exclusion diet solely because a baby cries.
Feeding and soothing before another formula change
During bottle feeds, hold your baby semi-upright with their head supported. Keep the bottle almost horizontal, offer pauses and stop when your baby has had enough. Never prop a bottle or force a feed. These steps follow NHS bottle-feeding advice.
Responsive feeding means watching hunger and fullness cues rather than insisting on a fixed amount. If feeds involve coughing, gulping or distress, ask someone qualified to observe a feed and assess teat flow. A vented bottle is equipment, not a proven cure; our feeding-bottle guide covers practical choices.
Try holding, gentle rocking and a calm setting. Keep a short record of crying, feeds and nappies to discuss at the appointment. If overwhelmed, put your baby safely on their back in an empty cot, step away briefly and ask someone for support. Never shake a baby. The NHS crying-baby guide has practical coping advice.
Frequently asked questions
Will a more expensive formula stop colic?
Price does not establish effectiveness. Decide on a formula change with a clear reason and a review plan, not a promise of rapid relief.
Should I switch to lactose-free formula for gas?
Not automatically. NHS guidance notes that lactose intolerance is rare in babies. Gas does not establish that diagnosis, and lactose-free milk may still contain cow’s milk protein.
Should I stop breastfeeding if my baby has colic?
Colic alone is not a reason to stop. Feeding support can help assess latch and milk transfer; a clinician can investigate additional symptoms if needed.
Can I dilute formula to make it gentler?
No. Use the exact mixing instructions on the container. Changing the water-to-powder ratio can make feeds unsafe; ask for help if preparation is unclear.
