Introduction
Formula allergies, especially to cow's milk protein, are more common than many parents realise.
Recognising early signs can help prevent discomfort, health issues, and even long-term complications for your baby.
Many Malaysian parents search for the best formula milk for baby 0–6 months, but even top brands like S26, Similac, and Dutch Baby may not suit every child.
Sign 1: Constant Crying or Colic
If your baby cries for hours even after being fed, changed, and burped, the formula might be to blame.
✅ Key Points:
Excessive fussiness or colic could indicate formula intolerance.
Crying usually worsens after feeding.
❓ FAQ:
Q: Can switching formulas reduce colic?
A: Yes, switching to a hydrolyzed or soy-based formula may help.
Sign 2: Skin Reactions Like Rashes or Eczema
Babies with formula allergies often show symptoms on their skin.
✅ Key Points:
Red, itchy patches.
Persistent eczema despite skincare.
❓ FAQ:
Q: Is eczema always a sign of formula allergy?
A: Not always, but it’s a common sign when paired with digestive or respiratory symptoms.
Sign 3: Digestive Problems — Vomiting or Diarrhea
Frequent vomiting, diarrhea, or gas can signal your baby isn’t digesting the formula well.
✅ Key Points:
Watch for foamy, watery, or green poop.
Digestive discomfort can affect weight gain.
❓ FAQ:
Q: Should I stop formula if baby vomits often?
A: Consult your pediatrician, but a change in formula is often recommended.

Baby may sound wheezy or congested even without a cold.
