If the infant cannot gain appropriate weight by frequent
feedings at breast, or with the use of pumped hindmilk,
or with fortified breastmilk, then infant formula may
temporarily be needed. Use of a hydrolyzed formula
reduces the risk of sensitizing susceptible infants to
allergies (Greer et al., 2008) or diabetes and may also
lower bilirubin levels (Gourley et al., 2005).
