Question:
My baby is 95 days old. I accidentally ordered Stage 3 formula and fed my baby a 160ml bottle of it one time. Will this cause my baby a lot of discomfort or harm?
Answer:
It is completely understandable that you are worried about your 95-day-old baby accidentally consuming Stage 3 formula.
Fortunately, feeding it just one time will not cause a major problem. Stage 3 formulas generally have higher protein and mineral contents, which can be a bit burdensome for a younger infant's digestive system. However, a single 160ml feeding will not cause any severe issues.
For now, please monitor your baby for the following symptoms:
• Increased fussiness or a bloated belly
• Vomiting or diarrhea
• Refusal to feed
Most babies might experience a little temporary stomach discomfort, but they generally recover quickly. Simply return to the correct stage of formula for the next feeding, and ensure your baby stays well-hydrated today.
When to see a doctor:
Please seek an in-person medical evaluation if your baby experiences any of the following:
• Continuous vomiting or severe diarrhea
• Refusal to feed for more than 8 hours
• Extreme lethargy or acting unusually sluggish
To prevent future mix-ups, always double-check the formula stage before feeding, and consider storing any incorrect or older stage formulas in a completely separate location. Try not to worry too much; your baby should be just fine!
