Neither Dexolac nor Lactogen is universally better for all babies. In a 6-month-old baby, vomiting, diarrhoea, and fever after using both formulas are more likely due to illness, such as viral gastroenteritis, feeding issues (e.g., incorrect dilution or feeding method), or temporary milk intolerance, rather than the brand itself. Most standard infant formulas have similar basic nutrition, so frequent switching can sometimes worsen stomach upset. The priority is to avoid further changes without medical advice and to obtain a pediatric review to assess for dehydration, infection, or possible lactose or milk protein sensitivity. A doctor may then decide if your baby needs a standard formula, lactose-reduced formula, or hydrolysed formula based on examination. Until then, give small, frequent feeds, maintain hydration with ORS if diarrhoea is present, and seek urgent care if fever persists, vomiting persists, or the baby shows signs such as reduced urine output, sleepiness, or poor feeding.

Aptamil Gold Stage 1 Infant Formula is formulated for babies from birth up to 6 months of age. It is intended to provide nutrition during this early stage when breast milk alone may be insufficient or unavailable. However, it should be introduced only under a paediatrician's guidance, who can assess your baby's individual nutritional needs and confirm whether this formula is appropriate.

Since your baby is preterm and vomited after consuming Aptamil Gold Infant Formula Stage 1 for the first time, do not continue feeding without medical advice. Vomiting in infants can occur for various reasons, but preterm babies have sensitive, immature digestive systems and often require formulas specifically designed for their needs. Please consult your paediatrician or neonatologist before giving this formula again. If vomiting persists, worsens, or is accompanied by poor feeding, lethargy, or dehydration, seek medical attention immediately.
