Hi, My son is now 6 months 7 days old. He was always on breastmilk. When he was 5 months, we tried Nan Pro 1. When he completed 6 months, we tries Lactogen 2  and Dexolac 2. Me and my wife is against cows milk for babies so we would not give that. In all the above cases, he either vomited and/or rejected the formulae entirely. Since his mother will be returning to job after another month so, we need a formulae he might accept. Please advise
