I am using formula for my son we first used Nestle Lactogen 1 and I felt he was atleast passing stools regularly but was spitting out badly even through his nose. Then my paediatrician recommended S26 Gold and said he will be regular but my son hasn't passed stools since we switched which was 3 days ago and the vomiting is worse he spits out almost everything and so has to feed often. Please help mama's he has colic and is constipated I want to help him.😢😢😢
