Management of Reflux in 2-Month-Old Infants

Initial Formula Selection and Feeding Practices

The American Academy of Pediatrics recommends starting with an extensively hydrolyzed protein or amino acid-based formula for a 2-4 week trial in formula-fed infants with reflux, as cow's milk protein allergy can mimic or exacerbate GERD symptoms in up to 42-58% of infants 1
A 2-4 week trial of extensively hydrolyzed protein or amino acid-based formula is recommended to assess symptom improvement in infants with reflux, with significant symptom decrease expected if milk protein allergy is contributing 1, 2
The American Academy of Pediatrics suggests adding thickening to the hydrolyzed formula with up to 1 tablespoon of dry rice cereal per 1 oz of formula if symptoms persist, but notes that this increases caloric density and can lead to excessive weight gain with long-term use 1
The American Academy of Family Physicians recommends reducing feeding volume while increasing feeding frequency to avoid overfeeding and gastric distension in infants with reflux 1, 2
Keeping the infant completely upright for 10-20 minutes after feeding for adequate burping is recommended by the American Academy of Pediatrics to reduce reflux symptoms 3

The American Academy of Pediatrics reports that 24% of formula-fed infants had complete resolution of GERD symptoms after 2 weeks of switching to protein hydrolysate formula with thickening and feeding modifications 1
Close monitoring of weight gain is recommended as the primary outcome measure by the American Academy of Pediatrics 4

The American Academy of Pediatrics recommends referring to pediatric gastroenterology if there is no improvement after 2-4 weeks of formula changes and feeding modifications, or if warning signs such as bilious vomiting or gastrointestinal bleeding are present 4
The American Academy of Family Physicians suggests referring to pediatric gastroenterology if symptoms suggest complications such as feeding refusal, irritability, or respiratory symptoms like choking or coughing with feedings 2

The American Academy of Pediatrics warns against overdiagnosis and overtreatment of reflux, as most "happy spitters" with uncomplicated reflux require only parental reassurance, not formula changes or medications 1
The American Academy of Family Physicians advises against premature use of acid suppressants in infants under 1 year, as they are ineffective and carry significant risks 2
The American Academy of Pediatrics recommends avoiding discontinuation of breastfeeding in favor of formula switching, and instead suggests maternal elimination of cow's milk and eggs if the infant is breastfed 1, 2
