Provide the one-week Food Frequency Diary B and instruct the parent/caregiver on how to complete this assessment Collect stool sample that was obtained in previous week at home Phone review (Day 7) Subjects will be reviewed at this time point by telephone to review if any clinical symptoms have occurred while ingesting study formula. If it is determined by the Principal Investigator that the subject has had any clinically significant reaction(s) to the study formula, the subject must return to the clinic for evaluation. Subjects will progress to Phase II and continue feeding with the formula they have consumed as part of the seven-day, post-challenge feeding period. Study Visit 3 (Day 14): Two weeks on formula Once subjects have been consuming their assigned formula for a two week period the following assessment will be carried out: Obtain weight, length and head circumference Collect Subject Diary 2a and Food Frequency Diary B Review of open feeding period and presence of any clinical symptoms Provide one-week subject diary (Subject Diary 3) to be completed the week before returning for Visit 4 and instruct parent/caregiver on how to record, clinical symptoms and stool characteristics in subject diary. Provide three-day Food Diary 1 to be completed the week before returning for visit 4 and instruct parent/caregiver on how to complete the food records Instruct parent to collect stool sample during the week before study Visit 4. Review study product requirement and dispense as necessary Study Visit 4 (Day 28): One month on formula Once subject have been consuming test formula for one month they will undergo the following assessment: Perform clinical assessment and SCORAD Obtain weight, length and head circumference Obtain stool sample collected by parent Collect and review Subject Diary 3 and Food Diary 1 Review study product requirement and dispense as necessary Study Visit 5 (Day 56): Two months on formula Obtain weight, length and head circumference Provide 3 day subject diary (Subject Diary 4) to be completed in the following week and instruct parent/caregiver on how to record clinical symptoms and stool characteristics in subject diary Provide three-day Food Diary 2 to be completed in the following week and instruct parent/caregiver on how to complete the food records Review study product requirement and dispense as necessary Study Visit 6 (Day 84): Three months on formula Obtain weight, length and head circumference Collect Subject Diary 4 and Food Diary 2 Provide one week subject diary (Subject Diary 5) to be completed in the week prior to the final study visit and instruct parent/caregiver on how to complete the food records, clinical symptoms and stool characteristics in subject diary Provide three-day Food Diary 3 to be completed in the week prior to the final study visit and instruct parent/caregiver on how to complete the food records Instruct parent to take stool sample during the week before the final study visit Review study product requirement and dispense as necessary Study Visit 7 (Day 112): Final visit - four months on formula or Early Termination Perform clinical assessment and SCORAD Obtain weight, length and head circumference Obtain stool sample collected by parent Collect and review Subject Diary 5 and Food Diary 3 Collect blood sample Ensure Parents/caregivers have returned all diaries to the appropriate clinician at each center Study personnel will review the forms with the parents/caregivers Parents/caregivers will return all partial and unopened cans of the test formula
