A multi-center, double-blind, controlled, parallel-designed, prospective trial intended to evaluate the nutritive effects of a partially hydrolyzed cow's milk protein infant formula on infant fussiness.

A multi-center, double-blind, controlled, parallel-designed, prospective trial intended to evaluate the nutritive effects of a partially hydrolyzed cow's milk protein (PHP) infant formula on infant fussiness. Formula tolerance and intake, sleep characteristics, stool characteristics, parental quality of life, and medically confirmed adverse events will be compared between i two study groups.

• Signed informed consent obtained from parent or legal guardian for infant's participation in the study
• Signed authorization obtained from parent or legal guardian to use and/or disclose Protected Health Information for infant from birth through the length of the study period
