A nurse in a pediatric clinic is assessing a 6-week-old infant whose parent reports frequent episodes of inconsolable crying, especially in the evening, lasting several hours and several weeks.
The infant has a normal physical exam, is gaining weight appropriately, and feeds well.
Which of the following interventions should the nurse recommend to the parent to help manage the infant's symptoms?

Choice A rationale

Providing tummy time immediately after each feeding is generally discouraged for infants, especially those with reflux or colic-like symptoms. It can increase pressure on the abdomen and potentially worsen discomfort or lead to spitting up. Tummy time is beneficial for development but should be done when the infant is awake and not immediately after eating.

Choice B rationale

Changing the infant's formula to a soy-based formula is not a first-line recommendation for managing inconsolable crying in a 6-week-old with a normal physical exam and weight gain. While some infants may have sensitivities to cow's milk protein, a formula change should only be considered after other potential causes, like colic, have been explored and under the guidance of a healthcare provider.

Choice C rationale

Administering omeprazole drops, a proton pump inhibitor that reduces stomach acid, is not indicated for a 6-week-old infant with inconsolable crying, normal weight gain, and feeding. Omeprazole is used to treat conditions like gastroesophageal reflux disease (GERD) with documented symptoms beyond typical infant spitting up. Routine use for crying is not recommended and could have potential side effects.

Choice D rationale

Offering soothing techniques such as swaddling and rhythmic rocking are evidence-based interventions for managing inconsolable crying in young infants, often associated with colic. Swaddling provides a sense of security, mimicking the womb, while rhythmic rocking can be calming and help regulate the infant's nervous system. These non-pharmacological approaches are recommended as initial management strategies for unexplained crying in healthy infants.
