Does anyone believe that milk formulas of the same line are just the same when it comes to content? That price range is just purely for the purpose of market segmentation? I'm referencing this post which became viral weeks ago, claiming that S26 and Bonna doesn't have any difference with each other. https://www.facebook.com/superbob.roque/posts/640682922750852

The difference is actually that S26 has DHA and AHA which can promote better brain development in babies. That being said, it doesn't automatically mean that if you use S26, your kids will be smarter than those who use Bonna. The best thing to do here would be to just talk to your doctor about it, and ask them which formula they would recommend for your baby.
