In breastfed infants , evidence suggests that a hypoallergenic maternal diet may be beneficial for reducing symptoms of colic .
In formula-fed infants , colic may improve after changing from a st and ard cow ’s milk formula to either a hydrolysed protein formula or a soy-based formula .
Fibre-supplemented formulae had no effect .
Infantile colic , the cause of 10–20 % of all early paediatrician visits , can lead to parental exhaustion and stress .
A systematic review was conducted to examine whether dietary change provides an effective therapy for  infantile colic .
Clinical Response to 2 Commonly Used Switch Formulas Occurs within 1 Day
Very fussy or extremely fussy infants were r and omized to receive :  soy-based formula ( Soy : n = 82 ) or a partially hydrolyzed cow 's milk protein ( CMP ) , low-lactose formula ( PHF : n = 77 ) in a multicenter , double-blind , r and omized , parallel , prospect i ve 28-day feeding trial . Body weight and infant formula tolerance were reported . Adverse events were recorded throughout the study . A significant reduction in mean scores of fussiness , gas , spit-up , and crying compared with baseline measures was observed in infants who received either Soy or PHF within 1 day of formula intake ; improvement in symptoms was sustained by study end . Stool consistency remained constant through day 28 in the PHF group , whereas stools in the Soy group became more firm by day 2 and did not return to pre study consistency . PHF , with a protein profile patterned more closely on human breast milk , improved symptoms of formula intolerance as well as soy-based formula
