This study is designed as multicentric, interventional, with two successive randomised, double-blind, crossovers. The aim of the study is to demonstrate the tolerance of an extensively hydrolysed anti-regurgitation casein-based formula in infants with cow's milk protein allergy. After a confirmation of the diagnostic, this demonstration will be performed with oral food challenge. Secondarily, a long term tolerance phase will be performed to get growth outcomes with a consumption of the formula compared with a non-enriched formula.
