Since they both offer great benefits, can you just use both or switch it up every once in awhile?

Choosing only one brand can be tough, they clearly both have their benefits and contain essential nutrients for proper development & growth. You may just want to switch it up on a monthly or weekly basis, or however you want to do it.

Despite the common belief that switching up infant formula may cause gastrointestinal problems like gassiness and also fussiness, this is actually not usually the case. I will not say this is not in the realms of possibility of happening, but normally this will not be a problem if you decide to switch up your baby food formula.

Switching between formula brands is not a problem, even though many parents wonder if doing so may cause fussiness or stool changes in their baby. In fact, you can even mix different brands of the same type of formula together if you feel that your baby responds better to a mixture of one brand with another…

Contrary to popular belief, spitting up or excess gas in your baby is usually not due to the type of protein in the formula.4 Still, switching between brands can help parents see if their baby has any reaction to a particular brand.
