You can change, there is some differencee in the formula used in the first 6 months and in the formula used after 6 months and 1 year.you can change, for example you can use brand a or brand b, but it should be for less than 6 months, different brands claim they are superior to each other, I would say if your baby is gaining weight on a brand, not much of gain by switching brands
