When it comes to formula, it's not as easy or straightforward as some people might think. There are so many brands out there, and unless your little one has a specific diet (because of a dairy or soy allergy, for example), it can be hard to decide which brand works best for you. Some parents may buy a can of one brand, find their baby isn't a fan, and need to switch. Or you may be using a particular brand, but see that another brand is on sale. But it is safe to mix formula brands? And can you switch up formula brands regularly?
Is it safe to mix formula brands?
Short answer? Yes! We know it can be nerve-wracking to switch or mix formula brands, but it's totally safe to mix them as long as you're following standard mixing instructions. You can mix two brands, or switch to a new brand. Make sure to pay attention to the ingredients in the formulas you're mixing or switching between; for most milk-based formulas, the ingredients will be more or less the same, and the same applies for soy formulas or other types of formula. There's no reason you can't mix two different brands or switch between brands. The only time you'd want to stick to one specific brand is if it'd been prescribed by your pediatrician for a specific reason.
Will The Baby Notice?
As we mentioned above, the basic ingredients in most formulas are the same. For example, all milk-based formulas will have lactose and cow's milk proteins. The small differences, such as whey proteins or oils used for fat, would more than likely not be detectable by an infant. But, babies can taste! And they may notice the difference in taste between brands. Some babies may also get gassy or fussy after having a particular formula, so if that's the case, just avoid that brand.
Why You Would Want to Mix or Switch Between Brands
Sometimes, a particular brand of formula just doesn't agree with your baby (they get fussy, gassy, or have excessive spit up). Or, your baby may not like the taste of a brand! Some babies develop a dairy or soy intolerance. In these cases, it makes total sense to switch or mix formula brands. There's no one-size-fits-all, and sometimes you have to try a few to find the one your baby likes best. Also, plenty of parents switch brands when one goes on sale, or mix formula brands when they don't have enough left in one can for a full bottle (don't want to waste any of that precious powdered gold!). But you can rest assured - switching or mixing formula brands is totally safe, and can actually help you find the best one for your baby.
