As a pediatrician I would reassure the parent that a single feed of concentrated formula is unlikely to cause any serious harm in an otherwise healthy 8-month-old infant like in your case.
In this case, instead of preparing Lactogen 2 as recommended (2 scoops in 140 mL), 3 scoops were added to 140 mL. This makes the formula more concentrated, meaning the baby has taken in slightly more calories, protein, and minerals and less water than intended.
What should you do now?
* Do not induce vomiting.
* Continue breastfeeding or give the baby’s usual feeds as per schedule.
* Ensure the baby remains well hydrated over the next few hours.
* Prepare all subsequent formula feeds correctly.
* There is no need to dilute the next feed to “compensate.”
Next Steps
Consult your pediatrician if the baby develops:
* Repeated vomitingss
* Refusal to feedings
* Excessive sleepiness or difficulty wakingup
* Significantly decreased urine output (fewer wet diapers than usual)
* Persistent irritabilit
* Any signs of dehydration (dry mouth, no tears while crying, sunken eyes
