How to Choose Formula for Preterm Infants
When selecting infant formula for preterm babies, parents should consider several factors: distinguishing between formula types, considering the baby’s weight status, reviewing nutritional composition, monitoring tolerance, and choosing reputable products. If persistent symptoms such as vomiting, abdominal distension, or stagnation in weight gain occur, prompt medical consultation and treatment are recommended.
1. Distinguish formula types: Preterm infants should initially be fed specialized preterm infant formula. Once their physical condition meets developmental milestones, they may gradually transition to standard infant formula. Breast milk remains the optimal feeding choice; when breast milk is insufficient, appropriately matched formula can be used as a supplement.
2. Consider weight status: Select formula based on the preterm infant’s birth weight and current growth status. Babies with low birth weight require high-energy formulas. Once weight gain catches up to the standard range, formula type may be changed—under professional guidance.

3. Review nutritional composition: Specialized preterm formulas typically contain increased levels of protein, fat, and minerals to support catch-up growth. Avoid formulas with excessive added ingredients, as these may overload the immature digestive system.
4. Monitor tolerance: When introducing a new formula, transition gradually and observe stool consistency and abdominal condition. If abnormalities such as diarrhea, abdominal distension, or frequent spitting up occur, promptly report them and adjust the feeding regimen accordingly.
5. Select reputable products: Purchase formula only through authorized channels and verify product registration information. After opening, store the formula in a cool, dry place and consume it within the specified shelf life. Never use formula of unknown origin.
In daily feeding, follow the principle of “small, frequent meals” to reduce gastrointestinal burden. Regularly monitor changes in the baby’s weight and length; avoid switching formulas arbitrarily without professional advice. Always burp the baby after feeding and closely observe overall physical responses.
