Infant versus noninfant formulas and cow's milk: Transition based on age or weight?

Area of Science:

• Pediatrics
• Clinical Nutrition
• Infant Feeding

Background:

• Infant formulas are designed for use up to one year of age.
• Transitioning to non-infant formulas or cow's milk is common at one year.
• Underweight infants may be at risk of excessive nutrient intake during this transition.

Purpose of the Study:

• To highlight potential risks of nutrient excess in underweight infants transitioning from infant formula.
• To present clinical cases illustrating this issue.
• To offer recommendations for managing formula transition in underweight infants.

Main Methods:

• Case series presentation.
• Review of nutritional intake following formula transition.
• Clinical assessment of patient outcomes.

Main Results:

• Several cases demonstrated excessive protein and/or electrolyte intake in underweight infants post-transition.
• These infants relied heavily on formula for caloric needs.
• Nutrient excess was linked to non-infant formulas and cow's milk.

Conclusions:

• Clinicians must carefully assess nutritional needs before transitioning underweight infants off infant formula.
• Individualized feeding plans are crucial for underweight infants nearing one year of age.
• Recommendations are provided to guide clinicians in managing this transition safely.
