Aw mama, that's frustrating talaga especially when it's pricey! Honestly, some babies are just super sensitive sa smell and taste ng formula, a few of us tried Similac Tummicare din and our little ones rejected it because of the scent, kaya it's not just you. If it's authentic from the official store, the smell might just be how that particular formula is, pero I'd suggest asking your pediatrician if you can try a sample of another variant or brand para sure na hindi lang ito sa baby's preference, sometimes a formula switch makes all the difference, at least you won't waste the rest of those boxes! Sayang talaga ang pera, but baby's nutrition matters more, so don't stress yourself too much about it.
